title: Facilitation of glutamate release in the ventromedial division of the globus pallidus during palatable taste stimulation in freely moving rats: real-time measurement.
abstract: To make real-time measurements of glutamate in the ventromedial globus pallidus (vGP) in rats during free ingestive behavior, a recently developed dialysis biosensor was employed. The glutamate level in the vGP increased in response to intraoral infusions of various fluids and voluntary ingestion of food pellets. Palatable fluids evoked greater responses than unpalatable fluids did, suggesting that glutamate in the vGP is involved in ingestive behavior.
