Although their focus is not specifically on the brain sciences, both Daniel and I are members of the Society for Psychological Anthropology, one of the sections of the American Anthropological Association. In order to become a member, individuals have to join the AAA, which can get to be a substantial investment. But, for no cost, you can check out the website of the Soc for Psych Anth. There’s a number of resources worth checking out, including syllabi generously contributed by members for their courses on psychological anthropology and a list of graduate programs that are particularly strong in psychological anthropology.
The Society for Psychological Anthropology also has a list-serv that doesn’t put too much spam in my inbox (I may regret posting this for that reason). To join the list-serv, go to the sign-up page.
