Striatal microcircuitry and movement disorders

AH Gittis, AC Kreitzer - Trends in neurosciences, 2012 - cell.com
The basal ganglia network serves to integrate information about context, actions, and
outcomes to shape the behavior of an animal based on its past experience. Clinically, the …

Dichotomous organization of the external globus pallidus

N Mallet, BR Micklem, P Henny, MT Brown, C Williams… - Neuron, 2012 - cell.com
Different striatal projection neurons are the origin of a dual organization essential for basal
