[Circadian rhythm sleep disorders]

22 Sep 2009 BACKGROUND: Circadian rhythm sleep disorders often lead to sleepiness and insomnia. These disorders are characterized by a misalignment between the intrinsic circadian rhythm and the external social and physical environment. MATERIAL AND METHOD: ... Read more...

Discharge profiles of identified GABAergic in comparison to cholinergic and putative glutamatergic basal forebrain neurons across the sleep-wake cycle.

21 Sep 2009 Whereas basal forebrain (BF) cholinergic neurons are known to participate in processes of cortical activation during wake (W) and paradoxical sleep (PS or P, also called REM sleep), codistributed GABAergic neurons have been thought to participate in ... Read more...

Sleep homeostasis modulates hypocretin-mediated sleep-to-wake transitions.

31 Aug 2009 The hypocretins (Hcrts) (also called orexins) are two neuropeptides expressed in the lateral hypothalamus that play a crucial role in the stability of wakefulness. Previously, our laboratory demonstrated that in vivo photostimulation of Hcrt neurons ... Read more...
