Vertebrate brains evolved to facilitate a diverse array of behaviors and internal cognitive processes. Theories of neural function have proposed that neural computation is organized within populations or ensembles of neurons. Here, we identify ensembles of neurons in the striatum, the main input nucleus of the basal ganglia, in which...
Habits are actions taken without conscious consideration of a goal. The distinction between habits and conscious, goal-directed actions has been made for millennia. Only comparatively recently, however, have results from biological psychiatry and neuroscience begun to shed light on the existence of separable neural circuits that underlie our intuitive perception...
