The Human Connectome
This immense scientific project aims to create a comprehensive map of the all the neural connections in the brain, an undertaking which has been fronted by the Human Connectome Project which is sponsored by the National Institute of Health in the US.
The Human Connectome Project aims to decipher the interactions of neurons and synapses in healthy, living adult humans. Mapping of the brain can be spit into certain scales, ranging from single neurons, to populations of neurons, to cortical areas. It is thought that once sufficient data is gathered we will be able to stitch each level together to form one large, comprehensive map.
With current technology we are currently unable to capture the brain’s activity at the cellular level without using invasive procedures. Mapping the connectome at this level usually requires a post-mortem and thus is not ideal.
At the macro scale which is at the level of clusters of neurons and fibers; recent methods and advances have seen non-invasive mapping emerge rather successfully. At this level functional magnetic resonance imaging (fMRI) is used in conjunction with tractography- a procedure used to demonstrate neural tracts. (x)

Friends often look alike. The tendency of people to forge friendships with people of a similar appearance has been noted since the time of Plato. But now there is research suggesting that, to a striking degree, we tend to pick friends who are genetically similar to us in ways that go beyond superficial features.
For example, you and your friends are likely to share genes associated with the sense of smell.
Our friends are as similar to us genetically as you’d expect fourth cousins to be, according to the study published this month in the Proceedings of the National Academy of Sciences. This means that the number of genetic markers shared by two friends is akin to what would be expected if they had the same great-great-great-grandparents.
"Your friends don’t just resemble you superficially, they resemble you genetically," said Nicholas Christakis, a physician and social scientist at Yale University and a co-author of the study… (Full article from The Guardian)
In the latest episode of the BBC’s Infinite Monkey Cage, Robin Ince and Brian Cox are joined by comedian Ross Noble and evolutionary psychologists Keith Jensen and Katie Slocombe to discuss whether humans are uniquely unique?
Applause gives smartarses a chance to show off at concerts – but there are signs this ‘social contagion’ may be on the way out
Clapping, scientists at Uppsala University in Sweden have reported, is a form of “social contagion”. What you’re clapping, apparently, is not as important as joining in with the people clapping all round you. “The cessation of applause is similarly socially mediated,” say the scientists, “but is to a lesser degree controlled by the reluctance of individuals to clap too many times.”
