Which theory of sleep would explain why Jon slept an extra four hours after running a marathon?
Sleep allows the body and brain to rest and repair itself.
Why is REM sleep sometimes called paradoxical sleep?
REM sleep is often associated with very vivid dreams due to the increase in brain activity. Because
the muscles are immobilized yet the brain is very active
, this stage of sleep is sometimes called paradoxical sleep.
Why is REM sleep referred to as paradoxical sleep quizlet?
REM sleep is also referred to as paradoxical sleep
because while the brain and other body systems become more active, muscles become more relaxed
. Dreaming occurs due to increased brain activity, but voluntary muscles become immobilized.
At what sleep stage does your breathing become more regular and your awareness of external stimulation decrease group of answer choices?
Stage N3 (deep sleep, or slow-wave sleep)
Breathing becomes more regular. Blood pressure falls, and the pulse slows to about 20% to 30% below the waking rate. The brain is less responsive to external stimuli, making it difficult to wake the sleeper.
What are the adaptive functions of sleep?
Adaptive Function of Sleep
Variations and adaptations
in cognition and behavior make individuals more or less successful in reproducing and passing their genes to their offspring
. One hypothesis from this perspective might argue that sleep is essential to restore resources that are expended during the day.
Why do eyes move in REM?
It is during REM sleep that our eyes dart about. This is also the stage of sleep during which we are most likely to dream. The movement of our eyes is
due to specific brain activity
that is characteristic of this stage of sleep. Research suggests that eye movements may allow us to change scenes while we are dreaming.

How many awakenings per night is normal?

six times per night
. As the body cycles through various stages of sleep, including deep sleep and REM sleep, it dips from shallower to deeper states.
What stage of sleep is 8 13 Hz?
In terms of brain wave activity,
stage 1 sleep
is associated with both alpha and theta waves. The early portion of stage 1 sleep produces alpha waves, which are relatively low frequency (8–13Hz), high amplitude patterns of electrical activity (waves) that become synchronized ([link]).
What stage of sleep is associated with learning and memory?
Based on these findings, Smith (1094, 1096) suggested that in humans,
REM sleep
is involved in the processing of procedural memory, whereas REM sleep plays no role in the formation of declarative memories, particularly with respect to simple learning tasks.
What are 3 theories of why we sleep?
Several prominent theories have explored the brain and attempt to identify a purpose for why we sleep, which includes the
Inactivity theory, Energy conservation theory, Restoration theory, and the Brain plasticity theory
.
What disorder makes you not sleep?
Insomnia
is a common sleep disorder that can make it hard to fall asleep, hard to stay asleep, or cause you to wake up too early and not be able to get back to sleep.
What are the four theories of sleep?
