Physiological Psychology Test 2 -chapter 9 sleep crossword (+notes)
Light does not enter the suprachiasmatic nucleausthrough rods and cones; it comes in directlythrough the __ pathway.
The photochemical responsible for our sleep-alert cycle is
REM may contribute to brain ______ in infants
Accordingto EEG studies, ____are those associated with day to day wakefulness.
Nocturnal enuresis is
The ______ triggers REM
During _____ we have low blood flow in our primary visual cortex and in our prefrontal cortex.
One proposed function of ___ is to allow our bodies to recover from waste products(free radicals).
slow wave sleep
Overexcitation of the reticular activating system produces symptoms similar to those seen in
The * is a small region of the hypothalamus that is the biological clock of an organism.
SCN Suprachiasmatic nucleus
A sx of narcolepsy; a "loss of tonus" the person just falls down like Someone turned off a switch
A sleep spindle is a sudden increase in wave ______
_____ activates behavior. almost all its neurons are found in the raphe nuclei in the reticular formation.
electrical stimulation of the ______ can induce slow wave sleep, and lesions supress it
__ is the primary symptom of narcolepsy
During REM sleep we have high blood flow to our ___ cortex
visual association cortex
______ is a disorder where people stop breathing periodicaly during sleep
sleep is thought to ____ the body
Most living systems exhibit a 24 hour cycle; these are called ___
the ___ (runs through the pons) wakes up the forebrain-- it activates the cortex
antihistamines treat allergies and cause drowsiness, therefore ___ must be involved in wakefulness
there are reports of people sleep eating and walking whilie taking this drug
stage 4 sleep is the ______ sleep stage
people who have this disorder do not experience sleep paralysis. thus, they act out those crazy dreams.
REM sleep behavior disorder
__ neurons are helping to hold the brain in a waking state
if we stay awake, the neuromodulator ___ accumulates in our bodies; and you'll see cognitive and emotional effects
These are thought to suppress cortical arousal in response to stimuli that the sleeping brain evaluates not to signal danger, and also to aid sleep based memory consolidation.
the ___ theory states that dreams are powered by the random spontaneous firing of neurons
activiation synthesis theory
one evolutionary theory of why we sleep is to avoid
the inability to fall or stay asleep
when we dont sleep it has been reported that we can exhibit Sx simmilar to those seen in______
the locus coeruleus is the major source of ____ in the brain
____ is normal so you dont have to act out your crazy dreams
one theory of why we sleep is that it conserves _____
the ______ theory says that we dream for wish fulfillment,- it is our unconscious attempt to fill needs that cannot be expressed or that go ungratified during waking hours
sleep may aid in memory ______
most dreams contain ___ themes
CIPA stands for congenital insensitivity to pain (and) anhidrosis. Anhidrosis is _____
lack of sweat
lack of sweat: ____
these brain waves are seen in relaxed meditation, BUT still awake
These brain waves are seen in wakeful, day to day activities
these brain waves are involved in daydreaming and light wakeful sleep
these brain waves are long and slow; they are involved in the deepest level of sleep
Sleep stage __: light wakeful sleep ; theta waves only
Sleep stage __: relaxed stage, eye movement stops; alpha and beta waves (also sleep spindles and K complexes!)
Sleep stage __: deep sleep, delta activity. Part of slow wave sleep SWS
Sleep stage __: deepest sleep, delta waves. Hardest to wake from. Part of Slow wave Sleep SWS. night terrors happen here!
A sudden increase in brain wave frequency ( the brain is trying to start sleeping )
a sudden increase in brain wave amplitude (suppressing cortical arousal in response to stimuli that the sleeping brain evaluates not to signal danger, and second, aiding sleep-based memory consolidation)
This part of sleep includes theta and beta waves. Also called paradoxical sleep. sudden paralysis also. 90 minute cycles
REM sleep Rapid Eye Movement
During this part of sleep, blood flow and metabolism decreases to 75% function. Suggests brain regions are resting
Slow Wave Sleep SWS
The CSF cleans this up as part of body restoration during sleep
What % of sleep is REM in infants?
50-70% (only 15% in older people)
Four presumed functions of sleep:
restore (the body)
This part of the brain is in slow wave sleep activation. if stimulated it can induce sleep or supress it.
If caffiene is present, or a person has ADHD, this part of the brainstem is affected.
Reticular activating system (includes reticular formation) RAS [arousal and sleep / wake transitions]
This part of the brainstem triggers REM sleep and paralysis
within the Pons... this is the major source of NE norepinephrine. If its removed, REM sleep ceases. "the blue location"
Locus Coeruleus [translates to "the blue spot" because of azure blue appearance]
this part of the forebrain is the switch for the process of sleep: SWS and REM
this brain area is involved in near death experiences.
Temporal parietal junction TPJ
This is a state of between awake vs. sleep
this neurotransmitter is mostly in the raphe nuclei (reticular formation)
In REM: whats the deal with the: visual association cortex
primary visual cortex and;
visual association cortex : increased bloodflow
visual and prefrontal: decreased bloodflow
= the set up of a hallucination. (or dream)
the term for guiding yourself to plan what you will dream:
Why dream? 5 reasons:
random neuron firing = weave a dream together to make sense of it
sleeping aids are a common cause of
sleep apnea is a symptom of _____
loss of tonous or paralysis
uncontrolled bizarre experiences during sleep in narcolepsy
A Tx drug for narcolepsy with unknown sites of action
neuropeptide involved in narcolepsy
SWS problems include:
sleep related eating disorders
OK. good job
when locked in a windowless room with no daytime ques...
photo sensitive input pathway for circadian rhythem
In the hypothalamus _________ controls the biological clock
SCN suprachiasmatic nucleus
photochemical (SCN) that regulates biological clock/circadian rhythem
