The location of a country on the earth says a lot about its climate, its neighboring countries, and the resources that might be found there. The location therefore determines what kind of country you would expect to find at that point.
The same seems to apply to the brain. Every network is located at a certain place, which determines its function and neighbors but also the kind of function that occurs there. However, the rules that describe the relationships different brain regions have to each-other were not well understood until now. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany, and the Forschungszentrum Juelich, together with an international team of collaborators, have deciphered two axes along which the human brain is organized. It was found that these axes are mainly determined by genetic factors.
One axis stretches from the posterior (back) to the frontal
