The brain must learn how to overcome these speed disparities if it is to create a temporally unified representation of the external world: if the visual brain wants to get events correct timewise, it may have only one choice: wait for the slowest information to arrive. To accomplish this, it must wait about a tenth of a second.
As humans fall asleep, body activity slows down. Body temperature, heart rate, breathing rate, and energy use all decrease. Brain waves slow down. The excitatory neurotransmitter acetylcholine becomes less available in the brain. [9] Humans often maneuver to create a thermally friendly environment—for example, by curling up into a ball if cold.
The human organism physically restores itself during sleep, occurring mostly during slow-wave sleep during which body temperature, heart rate, and brain oxygen consumption decrease. In both the brain and body, the reduced rate of metabolism enables countervailing restorative processes. [ 97 ]

There’s a difference between being totally over your day and sundowning. In addition to the symptoms listed above, sundowning can include verbal or even physical outbursts, Elhelou says.
The human brain has many properties that are common to all vertebrate brains. [258] Many of its features are common to all mammalian brains, [259] most notably a six-layered cerebral cortex and a set of associated structures, [260] including the hippocampus and amygdala. [261] The cortex is proportionally larger in humans than in many other ...
The study’s first finding is that sleeping between 7 and 9 hours each night was optimal for brain function and boosting cognitive ability. Sleeping less than 7 hours and more than 9 hours ...
