Take a look at work by DeLong out of Emory University, James C. Houk and
C. Gerfen. These individuals have contributed quite a bit to BG research.
In terms of new avenues of research, pallidotomy is current a hot topic
(surgery to relieve symptoms of Parkinsons)--- also look at recent work
on BG somatotopic organization and the role of BG in sensorimotor activity.
Hope this helps out abit and good luck!
