WebMuscarinic M2 stimulation induces behavioral wakefulness and cortical desynchrony in control dogs, whereas it induces cataplexy in narcoleptic dogs. It was recently revealed that hypocretin-containing neurons project to these previously identified monoaminergic and cholinergic regions where hypocretin receptors (Hcrtr 1 and Hcrtr 2) are enriched. Webdesynchrony EEG activity of 3.5–7.5 Hz that occurs intermittently during early stages of slow-wave sleep and REM sleep theta activity stage of sleep marked by presence of theta activity which indicates that the firing of neurons in the neocortex is becoming more synchronized this stage is actually a transition between sleep and wakefulness stage 1
