• Tetris Terror Therapy

    I pass through London Bridge area more or less every day. To avoid a dangerous junction, my route home involves cutting through Borough Market. Earlier this month three lunatics drove a van into innocent pedestrians and proceeded to stab random passers by. Fortunately for me I was out of town that night. Many others weren’t so lucky. Several people lost their lives and many sustained brutal injuries. Every single person that made it to hospital survived (at the time of writing), testimony to the extraordinary skills of the emergency workers, hospital medical staff and brave members of the general public who intervened. Yet for many of these people (1 in 3), long after the news has lost interest in the these tragic events, long after the physical damage to the victims’ bodies have healed, the psychological impact will endure for many months, possibly even years from now.

    Post-Traumatic Stress Disorder (PTSD) affects about one in three people who are exposed to a traumatic incidents like car crashes, sexual assaults, muggings or robberies, natural disasters and witnessing violent deaths in any context. It is particularly prevalent in people serving in the armed forces, those working for the emergency services and anyone getting caught up in terrorist attacks. Experiencing violence can lead to a host of debilitating psychological symptoms known collectively as PTSD. It can make leading a normal life difficult for those vulnerable to PTSD because harrowing memories of the frightening events can end up intruding into the experience of daily life. Over and over again, day and night, recollections of the horror force their way into conscious awareness in the form of flashbacks and nightmares.

    Now this may sound strange, but there is a relatively new body of evidence indicating that one of the best things those who witnessed the horrors of Sat 3rd June 2017 in London could have done in the immediate aftermath to reduce the likelihood of developing PTSD is to play the classic 1980’s video game: Tetris. Strange but true. This is because the neurobiology of memory tells us that the six hours following a memorable event is absolutely critical to memory consolidation and so offers a possible opportunity to disrupt it. In cases of PTSD the consolidation process appears to go too far. Memories of immensely emotionally-disturbing events can become enhanced to the point where they are automatically recalled on a regular basis, irrespective of where the person is or what they are doing, and comes accompanied by the kind of intense feelings of fear, anxiety and distress that were experience at the time that the atrocity was endured.

    Constant intrusion of such thoughts and feelings can be incredibly disruptive to normal daily function. Insomnia is very typical in people suffering with PTSD, which leaves the person frazzled and irritable. Other people can often have trouble grasping the full impact of the PTSD symptoms on the sufferer’s daily experience, and this lack of understanding can leave the victim feeling of guilty and somewhat isolated. Interventions to help people suffering with PTSD do exist, but their effectiveness seems to vary considerable from person to person. Ideally we could find a way to stop PTSD developing in the first place… prevention is, after all, always better than cure.

    Enter Cambridge University’s Professor Emily Holmes. In 2009, she and her colleagues published a paper describing an elegant, ingenious, yet very straightforward approach to reducing the incidence of flashbacks after a traumatising event. Ultimately the aim was to develop a cognitive vaccine that could disrupt the processes that would otherwise lead to the development of PTSD. Their study found that those who played Tetris for 20 mins or so shortly after watching a traumatic film depicting real people enduring tremendous suffering, experienced fewer flashbacks in the weeks that following than the control group who performed a different task in the aftermath.

    In 2017, Prof Holmes and her colleagues published another paper, this time the journal Molecular Psychiatry, describing a pilot study performed NOT with student volunteers in the context of a laboratory experiment as is usually the case with such experiments, but instead with emergency workers and medical staff in the context of a real life Accident and Emergency department of a major hospital. Early results look promising: they found a reduction in traumatic flashbacks in the first week after the incident and concluded that a larger study would be warranted to garner sufficient statistical power to establish whether or not these benefits extend to longer periods of time.

    Personally, I find the current data convincing enough that, should I ever be unfortunate enough to get caught up in one of these terrorist attacks, shortly afterwards (assuming I survive) you’ll find me playing Tetris on my phone in an effort to keep PTSD at bay. In conclusion, I’d like to wish all the victims, heroic passersby and emergency workers who were involved in that horrible attack a speedy recovery of both body and brain.

    In addition to these monthly blogs I tweet brain news daily (@drjacklewis). The new series of Secrets of the Brain is coming out on insight.tv at the end of the summer. And the Geek Chic’s Weird Science podcast I host with Radio X’s Lliana Bird is touring the South East of England over the summer at various festivals recording in front of a live audience. We’ll be at Latitude Festival at 17:30 on Sat 15th July with special guests Robin Ince and Helen Keen. We’ll also be at Womad on Sat 29th July. So if you want to come and see us live… get involved! Otherwise you can listen to all our podcasts on iTunes, Libsyn, Acast and more…

  • A Book Pairing for Summer 2017

    Certain restaurants like to suggest specific wines that go well with particular dishes. The crisp, citrusy, Sauvignon Blanc to go with a dish of lemon sole, or the full bodied, smokey Malbec to go with a sirloin steak. The flavours of the wine and the dish are often said to mutually reinforce each other, such that the combination is greater than the sum of its parts. Passing through an airport bookshop earlier this month I made a lucky spontaneous decision that demonstrated a similar effect is possible in the literary world. So I thought I’d share my discovery with you: I picked up two books, one fiction, one non-fiction, and they complemented each other perfectly. I would wholeheartedly recommend the following pairing.

    Over the past twelve months or so I’ve seen lots of people wielding a copy of Yuval Noah Harari’s SAPIENS – A Brief History of Humankind in planes, trains and automobiles. When everybody seems to be reading a certain book it always piques my curiosity. Either the marketing campaign was particularly effective or, more likely, each person who chose to buy it had been recommended it as a good read by a handful of people. As regular readers of this blog will know: I’m a sucker for Wisdom of the Crowd. And it did not let me down on this occasion because SAPIENS is an absolute cracker.

    A huge volume of well-packaged, condensed, easy-to-assimilate information that touches on the major milestones in our species’ prehistory including our encounters with other, now extinct, human species, the agricultural and industrial revolutions, and a wide variety of human empires that rose and fell through the ages is presented with great speed, style and finesse. The most gob-smacking revelation for me, overall, was mention of the genetic evidence suggesting that a fair chunk of European human DNA is of Neanderthal origin and a sizeable portion of Asian human DNA originated in the Homo erectus species. We’d covered a science story on the fact that Neanderthal’s were to thank for the keratin in our hair and nails on the Geek Chic Weird Science podcast, but I’d presumed that this was the case for all Homo sapiens, not just the European ones. The concept that the human species with which our ancestors had sexual dalliances differed according to whether the Homo sapiens in question happened to reside to the east or the west of the Eurasian land mass came at me like a bolt from the blue.

    Jean M Auel’s Clan of the Cave Bear is the first book in a series of works of fiction describing an orphaned Homo sapiens girl being adopted into a Neanderthal tribe. Access to evidence regarding how Neanderthals behaved, what they believed and the extent of their knowledge is inevitably scant given how long ago they were wiped off the face of the planet. But Auel’s account of their superstitions, social organisation and rigid thought processes seemed entirely plausible. I’ve always been a great fan of Bernard Cornwell’s books. I love his approach of sticking faithfully to the historical record regarding the Saxon and Viking invasions of Britain wherever it is available, but filling in the gaps with reasonable fictions that are entirely compatible with what is known from those times. I got the distinct feeling that Jean Auel takes a similar approach. Even when the storyline became slightly fantastical as the tribal witch doctor communes with the ancestral spirits to seek advice on the best course of action, the brews concocted by their medicine woman were certainly based in fact. And speculations regarding differences in the cognitive abilities of Homo sapiens and Neanderthal’s also seemed reasonable given what we can glean from the skulls in the archaeological record.

    Frustratingly, the further back into the history of our species we peer, the greater the uncertainty regarding the actual facts. I personally found the pairing of the facts presented in Sapiens A Brief History of Humankind with the fictional accounts of the nature of interactions between Neanderthals and Homo sapiens in The Clan of the Cave Bear to be an absolutely delicious antidote to this problem. And I hope you do too!

  • Virtual Reality Arcade coming soon…

    Please forgive the brevity of my recent brain posts.

    I’m working non-stop on my new book – due with the publishers at the end of the month.

    When I’m not writing, I’m finishing filming / voiceover for the new series of Secrets of the Brain.

    Haven’t had a day off for weeks!!

    I expect no sympathy, only  patience: normal service will resume later in the summer…

    In the meantime, I just wanted to share this small update:

    Four years ago I asked Mel Slater, Professor of Virtual Reality Environments and all-round legend, if he thought there was any chance that recent advances in VR technology might lead to the return of the video arcade …

    As it turns out, London’s First Virtual Reality Arcade opens this summer…

  • Do You Remember That Time…?

    Timehop is a reminiscence app for those that don’t already have Facebook. It pulls photos from your social media streams to remind you what you were up to a year ago, 5 years, 10 years ago etc. There’s nothing quite like a photo to trigger memories of a certain period of life. Sometimes I wonder if I would even be able to recall a tiny fraction of my life’s events in a world before photography. It’s usually the case that if a life event is deemed worthy of being captured in a photograph, then seeing it again will encourage a positive frame of mind. Only yesterday I overheard a relevant discussion between a pair of colleagues in my local supermarket. One showed the other a photograph of a family trip to Jamaica on his smartphone and the other murmured: “I love looking at old photographs, it’s just the best.”

    The damage that Alzheimer’s disease does to the brain regions that support retrieval of autobiographical memories can  eventually extinguish a person’s very sense of self, more often than not, the abolition of recollections from early on in life doesn’t occur until the end of the process. For most of our lives, from developing a sense of self in infancy, to ultimately losing it once and for all, our sense of who we are follows an arc that seems to be wholly dependent on the  accumulation of most poignant memories, often revolving around novel and emotionally stimulating experiences. They are a reference point from which we get our sense of who we are. They are physically manifested in extra synaptic connections in neural circuitry distributed all across the brain, far beyond the hippocampus famed for it’s involvement in the creation and retrieval of memories. This brain blog is about the cues that can trigger recollection of our life’s key experiences that are so important in defining to ourselves who we are.

    At first a newborn infant has no sense of self. At this stage, even the very senses it uses to understand the world around it have yet to develop to the point where reliable information can be gleaned regarding what’s out there. The brain first must be exposed to a vast torrent of sensory experiences that help to shape and mature brain areas that crunch the information coming in through the various sensory systems during early brain development. The capacity to actively explore the environment further enhances these memories for our early experiences, until sufficient experimentation of cause and effect results, miraculously, at some point during the second year of life (usually between 15 and 24 months) in the classic signs of awareness of selfhood. Infants recognise that the reflection in a mirror is themselves, as evidenced by attempts to wipe off a coloured mark that might have been surreptitiously smeared on their cheek.

    Our sense of self develops in childhood as we experience more and more significant, emotionally affecting life episodes, which are each logged away deep somewhere in the recesses of our mind. Foods and people we like and dislike. Places in which we experienced pleasures and pains. Circumstances associated with unpleasant emotions associated with hunger, cold and threats, others that predicted feelings of comfort, excitement and laughter. Life’s surprises and first time encounters dominate those memories that are most easily brought to mind.

    Once we look back on childhood from the perspective of a fully-grown adult some interesting quirks of memory start to become evident. First is that memories from our earliest years of life are wiped. This childhood amnesia manifests as a complete inability to recall much of what happened to us before the age of three or four. Perhaps the odd fleeting memory of one or two key events at the age of four at best, but nothing from the ages of 0-3 years old.

    The sense of smell has an astonishing capacity to remind us of early childhood memories. This can be accounted for by the fact that, of all our senses, the olfactory system is the only one that plugs directly into the brain’s cortex without first filtering through the thalamus. The thalamus is the brain’s major junction box through which the senses of vision, hearing, touch and taste are required to interface before being shuttled on for further processing at various dedicated patches of the crinkly outer surface of brain tissue. There are two major sites at which the sense of smell is generated according to the different types of gaseous chemicals detected deep inside the nostrils by hundreds of different types of olfactory receptor. One is on the underside of the frontal cortex and another on the medial (inward-facing) temporal lobes. The temporal lobes also house the hippocampus (fundamental to the creation of new memories) and the amygdala (critical for the production of emotions) perhaps explaining why scents tend to produce a powerfully emotional sense of reminiscence, typically evoking memories from before the age of 10.

    The reminiscence bump describes the observation that, further back than their most recent experiences, adults over the age of fifty are most likely to recall experiences from late adolescence and early adulthood (15-30 years old). Whether cues used to elicit important memories are pictures or individual words, the majority of autobiographical episodes that pop into our mind tend to come from this period of life. A period in which significant events mold our character and help to form our adult self.

  • 2016 in Review

    2016 has been quite a year:

    On the 3rd January I went for a dip in a freezing cold lake in the Dutch countryside with a man who has learned to control his immune system using breathing techniques in combination with cold water immersion.

    Between January and May I wrote a book Mice Who Sing For Sex with my Geek Chic podcast co-host Lliana Bird. That hit the shelves in October and flew off them in the run up to Christmas.

    I flew out to the USA to work with a pair of NFL superstars and a supercar test driver to talk about how high performance athlete‘s brains work compared to the rest of us.

    An unexpected opportunity to appear on the sofa with Rylan for Big Brother’s Bit on the Side gave me the opportunity to use five brightly coloured jelly brains as colour code for different brain functions and used them to explain the cause of various errant behaviours exhibited by some of this year’s contestants.

    Participating in a debate organised by the Wellcome Trust on the Latitude Festival’s Literature Stage opened my eyes to the Porn Perspective.

    My TV highlight has to be a very enjoyable weekend that I spent spy on some unsuspecting guinea pigs with the BBC’s Michael Mosley a TV presenter of considerable experience and acclaim. Meet The Humans (working title) will be broadcast at some point on BBC Earth throughout the world in 2017. I learned a huge amount about what being a TV presenter is really all about and felt truly privileged to work with him and a crack team of Science TV producers and directors from BBC Bristol. Seeing how they all handled what was a huge logistical undertaking, with so many moving parts that innumerable things could have gone wrong, was a real privilege. All hands on deck performed with tremendous competence, efficiency and good humour throughout; even when the pressure was on and Sod’s Law threatened to tip the apple cart.

    The most notable achievement of this year career-wise is that, for the very first time, a show I’ve presented has been deemed worthy of a second series; not to mention a runner’s up prize for Best Science Series of 2016 at the Association for International Broadcaster’s Awards. Not bad considering we were pipped to the post by a documentary about a near perfectly preserved 5,000 year old man thawed out from a melting glacier. That’s pretty steep competition and I was only too happy to concede defeat to a series documenting such an extraordinary scientific discovery.

    Looking forward to 2017 there’s already plenty of exciting projects in the pipeline. My third book Science of Sin, scheduled for publication next autumn, is coming on leaps and bounds. I’ve wanted to write a book about the light neuroscience might be able to cast on the topic of Why We Do The Things We Know We Shouldn’t for ages. I’m very grateful to Bloomsbury Sigma for the opportunity to immerse myself in such a fascinating and diverse body of science.

    Filming for Secrets of the Brain 2 is already underway and, after the intensive period of filming, editing and voiceover ahead in the next four months, that particular seires scheduled to be ready for broadcast on www.insight.tv (ch 279 on Sky) over the summer. Happily it seems we’ve been able to re-recruit most of the team from series one. It is fortuitous that we could get almost everyone back because there really is no substitute for prior experience with this kind of show.

    The speaking circuit this year has taken me all over London, to Cheltenham, the Midlands, Barcelona, twice to Cologne courtesy of ITV Global / Germany and as far East as Berlin. My Neuroscience of Creativity talk always seems to go down particularly well and the C-HR festival of Creativity and Innovation, which took place in a beautiful architectural space – an abandoned department store slap bang in the centre of Berlin – was no exception. I must have hit a new Personal Best by answering questions from the audience for longer than the actual duration of the talk itself (90min talk, 150min Q&A)!

    Of all the ways I communicate the fruits of neuroscience research to the world, it’s the face-to-face contact with live audiences that I get the most personal satisfaction from. People always seem to have burning questions about their own brains, their kids, their ageing relatives and it gives me great pleasure to share what I know with others. So if you have an event coming up for which you have need of a motivational speaker that brings something a little different to the event, why not get in touch? I’ve got five 60-90 min talks, I can take off the shelf: Boosting Performance, Neuroscience of Decisions, Neuroscience of Creativity, Dealing with Change and even one on Gender Neuroscience that has turned out to be pretty effective at encouraging greater equality in the workplace.

    That said I’m always happy to make something bespoke to fit the specific event. I’m always happy to stick around afterward if the crowd fancies making the Q&A a bit more informal.

    All that remains to be said is to wish you happy holidays and a fantastic 2017.

    If you’d like to follow me on Twitter (@drjacklewis) you’ll get my daily tweets that flag the best of the neuroscience news that hits the lay press. The Geek Chic Weird Science podcast is still going strong after nearly three years, which can be accessed through iTunes, Podbay, Libsyn and many other podcast providers so if you fancy taking a lighter look at the world of science, that’s your badger. And finally, you’re at a loose end over the holiday season and fancy a break from the usual TV fare, then why not catch up on the (nearly) award-winning Secrets of the Brain by pointing your internet towards www.insight.tv (my parents are actually doing that right now…)

    Happy Christmas

  • Fighting Dementia with Sea Hero Quest

    shq-logoAs we move around in the world we develop a sense of how to get from A to B. This relies heavily on the hippocampus, a brain structure nestled deep within each of the temporal lobes, responsible for many functions vital to cognition such as memory and navigation. This is the brain structure famed for becoming physically larger as a result of all the practice driving around London that the drivers of London’s famous Black Cabs have to accrue before they can pass “The Knowledge.” Whilst their memory for the 25,000 roads and 20,000 major landmarks that enable them to instantly reel off the route they’d take to get from one place to another is extraordinary, for the 33% of those born in 2015 will live long enough to develop dementia at some point in their lives this situation is reversed. Difficulties with navigation, even familiar routes between places visited many times before, is one of the problems in daily life that can herald the approach of full-blown dementia. Understanding the normal trajectory of changes in navigational ability over the lifetime of a health brain is a vital first step. With or without dementia our abilities to memories complex routes becomes slowly but surely compromised by the normal processes of age-related cognitive decline. We need to know what is normal for each age group before we could be in a position to use a steeper than normal decline in navigational ability as an early warning signal, ideally before any memory deficits have had a chance to rear their ugly heads. As our understanding of the metabolic processes that lead to various forms of dementia improve, this early warning could prove to be a vital mechanism in triggering prophylactic treatments early enough to slow down disease progression.

    memoriseHugo Spiers, a memory researcher and neuroscientist at University College London, launched a smartphone game in 2016 called Sea Hero Quest, which aims to do just this. Over 2.5 million people have played this surprisingly fun, engaging and challenging game so far, generating the equivalent of an astonishing 9,400 years worth of lab data. The game involves memorising a map of waterways around which a series of numbered buoys have been distributed. Once you’ve planned the journey you’re going to make and tucked it away in your working memory, the map is then taken  away and your job is then to steer your little fishing boat (increasingly customisable as you progress through the game) by tapping the left or right side of the touch screen. The terrain varies from idyllic sandy paradises to rainy, foggy, bumpy rides across perpetually undulating swell. Thanks to the funding from Deutsche Telekom and Glitchers – the tech-gurus who actually created the game – the graphics are beautifully rendered, the gameplay is smooth and unlike most games designed to answer important scientific questions, every aspect of the user experience is highly polished. As was the delivery of the first results announced at SfN 2016 and summarised below by the man himself…

     

     

    buoyPersonally I was surprised by how hard some of the levels were. I play a lot of brain training games (e.g. PEAK Review, BRAIN AGE 2 Review ), just to keep myself up to date on the latest offerings, and am now accustomed to finding myself able to get maximal scores on most categories of games pretty quickly through daily play. Not Sea Hero Quest. Once I got past the easier earlier levels, I often found myself getting lost in the mist, or going round and round in circles having forgotten how to get from buoy 3 to buoy 4. As a consequence, not only did I help scientists like Hugo Spiers and colleagues from the University of East Anglia and Alzheimers Research UK to generate data (anonymously, you only have to give your age) but I also got an insight into what the future might have in store for me should I become one of the unfortunate 1 in 3 that get clobbered by dementia in my post-retirement years. As you progress from level to level you periodically get to chase down one of a large variety of sea monsters. Having dodged innumerable obstacles along the way the monster in question eventually leaps out of the water at you and your task, is to resist the temptation to hit the button on your camera to take a photo of the rare and exotic sea beast in question, until the very last second when the captured image is at its most aesthetically pleasing.

    Overall, I found playing this game great fun, very challenging at times and doubly satisfying knowing that it would, in some small but meaningful way, help science to get some much needed answers about how the human brain keeps track of where it is and where it’s going in health, so we can better understand when this system breaks down in disease.

    img_1517I would just like to take a moment to applaud @HugoSpiers and collaborators for finding a way to genuinely enable people to #gameforgood. Hats off to you all… your Cannes Lion was thoroughly well deserved!

  • Announcing the Birth of our Beautiful New Book

    On the 6th October 2016 the book of the podcast that is Geek Chic Weird Science hit the shelves of bookshops all over the UK. A couple of days prior to this my co-author (and co-presenter of the podcast) Lliana Bird and I threw a little party to celebrate this milestone with a few family and friends.

    micewhosing_twitpic3dd4078I’m quite literally just running out the door to record our 60th podcast tonight! For those who’ve never had a chance to listen, every couple of weeks we talk about the latest weird and wonderful science stories to hit the press in the past few days. We tend to favour the conversation starters: the whacky techy tales that people might pull out of the bag around the dinner table, at work/school or in the pub to spark a conversation around the latest strange/surprising scientific discoveries.

    By the time we got about episode 50 we had an archive of about 200 or so of these science stories. So we thought: why not write a book. Happily the publisher Little Brown were prepared to publish it under their Orbit imprint and with only four months to bash it out we just about managed to hit the deadline. It’s a bit ragged in places, a few errors and slight inaccuracies here and there, but given the incredibly limited time we had to get it done I think we did a pretty good job.

    We’ve had some tremendous reviews from the likes of Brian Cox and the Times Science editor. Some of our stories have already been picked up in the NME and the London Metro. And with Noel Fielding’s beautiful original artwork adorning the front cover we have high hopes for some good sales over Christmas.

    mumanddadWe dedicated the book, with love to our parents, but also to Richard Boffin who has been our “sound guy,” editing our podcast, adding the music and sound effects and getting it up on iTunes, libsyn, podbay (click any of these links if you want to have a listen) and various other podcast media month after month for over two years now. Thanks Boff – you’re a legend!

    A huge thanks must also go to our thousands of podcast listeners around the world – we’re really grateful for your continued support – and we really hope you enjoy the book, not to mention the quirky and amusing illustrations our talented artists conjured up for us.

    Mice Who Sing For Sex by Lliana Bird and Dr Jack is now available to buy online and in all good bookshops like, my personal favourite, Waterstones.

  • Porn Brain

    Last summer I was invited by the lovely people at the Latitude Festival to participate in a debate at the Literature Tent on the impact of online pornography on society.

    pornperspectiveonstage

    It was chaired by Dr Suzi Gage (@soozaphone) of Bristol (and by now Liverpool) University, known for her popular Guardian science column and podcast Say Why to Drugs. The other panelists were Martin Daubney (@MartinDaubney), former editor of lad’s mag Loaded for eight years and theatre-maker Christopher Green (@Kit_Green) creator and player of comedy Country ‘n’ Western heroine Tina C.

    My role was to bring the neuroscience perspective, Martin the media perspective and Chris was taking the arts angle. I got prepared quite a few weeks in advance and was stunned by what I found lurking in the academic literature. So I thought I’d share my main findings with you here in this month’s blog.

    When people think of addictions, compulsive consumption of various psychoactive substance is usually the first thing to spring to mind. Much research has demonstrated a hyper-responsiveness of the reward pathway – the ventral tegmental area in the midbrain and nucleus accumbens in the ventral striatum in particular – to drug-related images in the brains of people addicted to recreational drugs like, for example, cocaine. This body of research also demonstrates that the activity generated in the reward pathways of drug addicts to pleasant images of scenes unrelated to drugs, is somewhat diminished compared to non-drug takers. In other words, excessive consumption of drugs seems to subtly rewire the reward pathway so that it becomes more sensitive to visual scenes relating to their preferred recreational drug and less so (than normal) to everything else. It seems this is not just limited to drugs, a similar impact on brain function is seen in people who over-consume porn too.

    img_0510It is important to bear in mind that the reward pathway is not only important for generating feelings of happiness when we participate in pleasurable activities, but it’s also instrumental in predicting what choices might bring us rewards in the future, which means it is critically involved in decision making. It’s role in helping us evaluate the benefits of one option over another extends to the point where this system, in combination with other nearby brain areas, can be thought of as providing the very drive that motivates us to pursue one course of action over another.

    In recent times, research into excessive consumption of various products accessed through the internet – online gaming, gambling and pornography, to name but a few – also leads to behaviours that have all the hallmarks of addiction, not to mention the altered neurological responses outlined above. There has been some resistance to this idea in various academic communities, but the movement to have these “arousal” addictions included in handbooks of psychiatric illness symptom classification, and in particular the DSM-5, is starting to gather momentum.

    On the basis of a huge survey investigating the pornographic consumption and sexual experiences of 28,000 Italian teenagers it seems that, for about one in ten boys who consume explicit online pornography on a daily basis, the habit is interfering with their ability to engage in real life sexual activities:

    It starts with lower reactions to porn sites. Then there is a general drop in libido, and in the end it becomes impossible to get an erection

    Carlos Forsta, President of the Italian Society for Andrology and Sexual Medicine.

    This may at first glance seem to fly directly in the face of the stereotype of the ultra-horny teenage boy, brimming full of the very sex hormones that would usually ensure a hair-trigger sexual response to any possibility of coitus. But in light of research conducted many years ago by joint winner of the 1973 Nobel Prize for Physiology or Medicine, Nikolaas Tinbergen, it starts to make a lot more sense. In experiments conducted with “supernormal” stimuli, he observed that birds preferred to sit on larger than normal and / or more colourful eggs constructed from plaster, rather than their own real eggs. Similarly, herring gull chicks would peck harder and more often at a fake adult herring gull beak with brighter or more numerous red spots than the real thing, in a vain effort to elicit a regurgitated dinner. The point is that the larger than real life stimuli seem to have short-circuited the birds’ primal instincts leading to a preference that would ultimately be deleterious to the survival of the bird’s progeny.

    It seems that the ubiquitous availability of explicit internet pornography is leading to a similar scenario in modern day internet addicted teenage boys. A subconscious preference for artificial, supernormal, explicit porn over actual sexual partners seems to be occurring with alarming regularity in adolescents who let their penchant for titillating pornographic films get out of control. In his TED talk entitled “Why I stopped watching porn” Ran Gavrieli gives an excellent and compelling account of some of the key differences between what pornographic films actually show and the relatively tame sensory stimuli involved in genuinely satisfying, intimate sexual behaviour between consenting adults.

    Essentially, he points out that themes typically conveyed on free online porn sites, such as female subordination and extreme close ups of penetration to name but a few, are the human sexual equivalent of the brightly coloured, super-sized eggs and beak markings from Prof Tinbergen’s experiments (just not in so many words!). Porn is a supernormal stimulus, dominated by explicit close ups of penetration that you simply can’t reproduce in reality (the penis and eyeballs will always be separated by a set distance, unless you are exceedingly flexible, of course). Inevitably the real thing pales into insignificance by comparison after sufficient daily use of explicit porn of virtually infinite variety. No wonder boys are struggling to get it up!

    img_0538This isn’t to say that there is no place for pornography in society. Regardless of your attitudes on this topic, it certainly isn’t going away any time soon. However it may be useful for porn fans to bear in mind the concept of everything in moderation. Once one genre of porn is no longer arousing there are many other categories to choose from. Once the relatively soft porn is no longer stimulating, casual browsing will always yield more explicit options. Eventually the kind of sexual activities we are likely to have access to in real life become insufficient to yield an erection for long enough to reach climax, which will inevitably lead to relationship problems. And nobody wants that.

    The good news is that abstinence from pornography is usually sufficient to enable normal biological sexual function to eventually return. Interestingly, in older men this takes two months, whilst in younger men it can take much longer: four to five months. Find out more in the Latitude Podcast of the Porn Perspective Debate.
