The present study is an attempt to demonstrate Chemosensitive neurons within the area postrema (AP) electrophysiologically. Three types of Chemosensitive neurons were identified: 1. 1) glucose-responsive neurons that may participate in control of blood glucose and satiation, 2. 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. 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.
