Hi there,
Are you interest in Cognitive Science through Psychology?
I am currently working on an MSc in Cognitive Brain Science and Behaviour - Psychology and am looking at schools for my PhD.
If you are I would suggest looking at Carnegie Mellon. It has been recommended to me by several of my current Profs as well as some friends who are currently attending. They are ranked highly - especially in the cognitive sciences.
I would also look at the University of Missouri - again an excellent Cognitive program that has come highly recommended to me.
Hope this helps!
