Effects of hypocretin-saporin injections into the medial septum on sleep and hippocampal theta.

Gerashchenko D, Salin-Pascual R, Shiromani PJ (2001) Effects of hypocretin-saporin injections into the medial septum on sleep and hippocampal theta. Brain Res 913:106-115. doi: 10.1016/s0006-8993(01)02792-5

Summary: Hypocretin, also known as orexin, neurons are located only in the lateral hypothalamus. Recently, the loss of these neurons was shown to be associated with narcolepsy. The authors used orexin-SAP (100 ng/0.5 µl; Cat. #IT-20) to eliminate parvalbumin and cholinergic neurons (orexin B receptor-expressing) in the rat medial septum. They used 192-Saporin (1 µg/ 1 µl; Cat. #IT-01) to contrast the effect and eliminate only cholinergic neurons (NGF/p75 receptor-expressing). Hippocampal theta activity was completely eliminated in orexin-SAP treated rats by day 12, suggesting that orexin neurons influence cognitive processes critical for survival.
