Brain size and political affiliation

I came across an interesting mental health item on the radio 4 Today Programme. Brain changes according to our experience. The anterior cingulate and the amygdala are larger in those who vote conservative and smaller in those who vote liberal (check these facts).

I used to be a neuroscientist and I find the relationship between brain and environment facinating. Anyone interested in mental health cannot ignore the importance of the newer imaging techniques to throw light on brain functioning.

Below is the audio file link from the BBC.
