Pathologies of action control: Amygdala-striatal interactions and the development of habits.

点击翻译按钮获取中文摘要

Changes in basal ganglia function, whether produced by neurodegenerative disorders, stroke, injury or disease, can produce pathological changes in action control. This proposal will assess the role of amygdala afferents on basal ganglia structures, most notably the dorsal striatum, in this process. Using an animal model we will compare the role of central and basolateral amygdala inputs to striatum in decision-making, choice and the transition of actions to reflexive, habitual responses.
