Abstract

Highlights: Goal-directed and habitual modes of behavioral control can be behaviorally dissociated. Recent work reveals distinct contributions of striatal cell populations to goal-directed actions and habits. Corticostriatal plasticity as well as striatal interneuron plasticity are implicated in habit formation. Habitual actions and learned behavioral sequences share some common mechanisms. Abstract : Habits have been studied for decades, but it was not until recent years that experiments began to elucidate the underlying cellular and circuit mechanisms. The latest experiments have been enabled by advances in cell-type specific monitoring and manipulation of activity in large neuronal populations. Here we will review recent efforts to understand the neural substrates underlying habit formation, focusing on rodent studies on corticostriatal circuits.
