University of Rochester

A ventral region of the forebrain implicated in consciousness and sleep. Constant slow wave sleep in the isolated forebrain is resultant from the basal forebrain. Electrical stimulation of the basal forebrain can induce SWS sleep, whereas lesions can suppress sleep. Within the basal forebrain, neural circuits regulate activity of GABA-ergic neurons that project their axons to two targets: tuberomammillary nucleus and the reticular formation. 
- tuberomammillary nucleus
- reticular formation

Basal Forebrain

Basal forebrain image citation

A region in the basal hypothalamus, near the pituitary stalk that plays a role in generating SWS. This is where stimulation of GABA(A) receptors promotes sleep, and seems to be the ones acted on by general anesthetics. 

Tuberomammillary Nucleus

An extensive region of the brainstem involved in arousal. Electrical stimulation of this region activates the cortex. Lesions result in persistent sleep.
