Q
neural basis of sleep
A
As homeostatic drive for sleep accumulates, circadian drive for arousal decrease. For example, we awaken in the morning with little of no homeostatic sleep drive.
This increases as we are awake, but wake is maintained by progressively increasing circadian drive for arousal.
By late evening, circadian drive for arousal decreases and sleep is initiated because of pressure from homeostatic drive.
