Salk Institute -- Jin Lab -- Interneurons (IMAGE) Salk Institute Caption Green dots across top third of image indicate neurons in cortex, a brain region outside striatum that nonetheless directs information to PV interneurons in striatum; scattered green dots in middle third indicate striatal PV neurons; large vertical green-yellow crescent near bottom right indicates thalamic reticular nucleus (TRN), shown in current study to connect to striatal PV neurons. PV interneurons are thought to integrate sensorimotor information for action control and learning. Credit Salk Institute Usage Restrictions with credit and related coverage.
