I'm a physics student and I graduate in a few months. I have been looking for PhD's because I want to carry on learning physics but have so far struggled to find a PhD subject that really caught my eye.
I do, however, have an interest in the brain, the mind and consciousness (although I have no formal education in any of that). It occurred to me that if I could continue my studies in something that combined both physics and brain/mind/consciousness stuff, that would be perfect. However, googling around has not really turned up anything helpful so I thought I would ask here.
Does such a branch of physics even exist, and if so, is it active in 2011?
