A Year of BrainTweets – Which is Your Favourite from 2012? by Dr Jack Lewis

By Dr Jack

There is an awful lot of great information out there on the internet. But, as we have all no doubt experienced, there is also a load of old rubbish to wade through before you find those nuggets of wisdom. When I comment on twitter, anything labelled with #neuroformed (short for neuroscience-informed) is, in my opinion, a grain of brain-related wheat – a news article, abstract, insight or quote – that I’ve chosen to give my seal of approval to, flagging it as interesting, relevant and worth a few moments of your attention.

Sex on the Brain by Dr Jack Lewis

By Dr Jack

Hypothalamus’s PVN (red) prepares the body for sex by sending a torrent of electrical messages along neurons within the spinal cord which ultimately releases a cocktail of neurotransmitters into the genitals.

MEMNEON is a fun, challenging and highly-addictive smartphone game that will increase working memory and thus (according to research by Torkel Klingberg) improve your IQ! Even Stephen Fry – the God-of-Twitter himself – tweeted that MEMNEON was driving him “delightfully dotty.” High praise indeed! The creative director behind Memneon was Steve Turnbull, who would probably feel that for me to suggest that it is “Simon” for the 21st century, would be selling it short. I would disagree. Simon was the original brain training device and, as such, decades ahead of the game. Memneon is like Simon on a high dose of amphetamines.

Man the Manipulator by Dr Jack Lewis

By Dr Jack

Iterative cycles of human brains adapting to environments and environments being adapted by human brains have enabled our species to thrive in a wider variety of ecological niches than any other mammal across the length and breadth of the entire globe. Of vital importance to our adaptability is the emergence of cognitive faculties enabling us to circumvent the painstakingly slow processes involved in evolutionary change that drive behavioural adaptations in most other multicellular species.
