Neural correlates of behavior in the rodent striatum

The striatum consists of GABAergic projection neurons and various types of interneurons. Despite their relative scarcity, these interneurons play a key role in information processing in the striatum. We use multielectrode arrays to record the activity of striatal projection neurons and interneurons in behaving rodents. By comparing their responses we test the ability of the striatum to encode behaviorally relevant information such as movement and context.
