The human sleep cycle repeats itself about every
90 minutes
Patrick has just entered REM sleep. Which of the following is he likely to experience?
Body paralysis
How is the hypothalamus involved in sleep?
In response to decreasing light the hypothalamus' suprachiasmatic nucleus causes the pineal gland to increase production of melatonin, leading you to sleep.
After flying from California to New York, Arthur experienced a restless, sleepless night. His problem was most likely caused by a disruption of his normal
circadian rhythm
Alpha waves are associated with
relaxed but awake state
The rhythmic bursts of brain activity that occur during NREM-2 sleep are called
sleep spindles
The impact of circadian rhythms is best illustrated by
fluctuations in energy level and alertness across the span of a day
Researchers have demonstrated that people trained to perform tasks recall them better after a night's sleep than after several hours awake. This finding suggests that sleep
is involved in the memory process
REM sleep is called paradoxical sleep because
our nervous system is highly active, while our voluntary muscles hardly move
The large, slow brain waves associated with deep sleep are called
delta waves
