title: Chemosensitive neurons in the area postrema of the rat and their possible functions.
abstract: The present study is an attempt to demonstrate chemosensitive neurons within the area postrema (AP) electrophysiologically. Three types of chemosensitive neurons were identified: 1) glucose-responsive neurons that may participate in control of blood glucose and satiation, 2) sodium (osmotic pressure)-responsive neurons that may contribute to control of sodium and water balance of the body fluid and may be involved in salt appetite, 3) nausea-related neurons which respond to excess distension of stomach and LiCl as well. They may play a role in formation of conditioned taste aversion.
