Table 1.

Number and firing rates of neurons recorded from the preoptic area (POA) and basal forebrain (BF). State-dependent neurons within the POA and BF are classified as sleep-on, wake-on, or state-indifferent, and sleep-on neurons are further subclassified as AS-on or wake-on/AS-on. Mean ± S.E.
