Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The sleep-wake cycle is controlled by?
A
The amygdala
B
The hypothalamus
C
The pineal gland
D
The hindbrain
Explanation: 

Detailed explanation-1: -Sleep is one of the most important physiological functions in mammals. It is regulated by not only homeostatic regulation but also circadian clock. Several neuropeptide-producing neurons located in the hypothalamus are implicated in the regulation of sleep/wakefulness.

Detailed explanation-2: -Your body’s internal clock is controlled by an area of the brain called the SCN (suprachiasmatic nucleus). The SCN is located in the hypothalamus.

Detailed explanation-3: -An important source of sleep-related inhibition of arousal arises from neurons located in the preoptic hypothalamus. These preoptic neurons are strongly activated during sleep, exhibiting sleep/waking state-dependent discharge patterns that are the reciprocal of that observed in the arousal systems.
