title: Dopamine depletion in a striatal subregion disrupts performance of a skilled motor task in the rat.
abstract: Unilateral 6-hydroxydopamine injections into the lateral neostriatum disrupted the ability of rats to retrieve small food pellets with the contralateral forepaw. Similar injections into the medial striatum did not interfere with performance accuracy. Dopamine assays indicated that of the 5 striatal subregions analyzed, the lateral striatum at the level of the anterior commissure was most directly related to the behavioral deficit. The behavioral results are interpreted as providing evidence in support of a sensory role for the lateral striatal dopamine system.
