What part of the brain controls dreams and sleep?
The whole brain is active during dreams, from the brain stem to the cortex. Most dreams occur during REM (rapid eye movement) sleep. This is part of the sleep-wake cycle and is controlled by the reticular activating system whose circuits run from the brain stem through the thalamus to the cortex.
How does the hypothalamus control sleep?
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.
How is sleep regulated?
Sleep is regulated by two overlapping but distinct systems—the circadian system and sleep/wake homeostasis. 5, 6 The circadian system endogenously synchronizes biologic rhythms, including sleep, cyclically with the 24-h day and is adjusted through the influence of exogenous factors.
What regulates the pineal gland?
The pineal gland receives adrenergic innervation, which activates a cascade of circadian events that leads to the nightly formation of melatonin from serotonin. Serotonin is present at high levels in the pineal gland during the day and increases further at night in the absence of melatonin formation (Sun et al., 2002).
What are the 2 components of sleep regulation?
Researchers explain that sleep regulation has two components: Build-up of homeostatic sleep drive. Circadian rhythms.
