What is the Role of the Brain in Sleep Regulation?
The brain plays a crucial role in sleep regulation through a complex network of neurons and neurotransmitters. The hypothalamus, particularly the suprachiasmatic nucleus (SCN), controls the circadian rhythms, which influence sleep-wake cycles. The brainstem communicates with the hypothalamus to control the transitions between wakefulness and sleep. Additionally, the pineal gland secretes melatonin, a hormone that promotes sleep.
