Another Year of Brain Tweets
Each year I look back on a year’s worth of brain tweets to see what’s been trending recently… here they’re carefully sorted & categorised for your delectation
Hot Topics in Neuroscience by Dr Jack
I finally took the time to categorize and tally as many of my recent Tweets as I could get my hands on to clarify what topics have been hottest in recent times.
Sex on the Brain by Dr Jack Lewis
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. In both men and women this leads to vasocongestion whereby the genitals become engorged with blood – leading to an erection in men and lubrication, increase in vaginal depth and diameter in women.
Lust, Love & Long-Term Bonding by Dr Jack
Behaviours associated with lust, love and long-term bonding developed through evolution of separate but overlapping brain systems. Lust encourages coitus on a relatively indiscriminate basis: ensuring that genes are passed on to the next generation. Love involves a sexual preference for an individual considered in some way superior to the competition. And long-term bonding encourages fulfilment of parenting duties.
