rhythm sleep
nathaniel Kleitman and eugene aserinsky (1995) examined the eye movement slows down when people started to sleep at night, finally the fact the eye movement sleep slow but not very fast.

rapid eye movement (rem) sleep is characterized by periods of pergerakana eyes, loss of muscle, and the dreams that look real. period brakes seem to alternate with periods in which the eyes do not move that fast, or is also a non-rem sleep (NREM), in each cycle of 90 minutes. brake period runs along most minutes to an hour, with an average of approximately 20 minutes. This time period begins, the pattern of electrical activity in the brains of people who sleep switch so like the person in the situation, and be fully awake.



when we first climbed into the sleeping area, close your eyes and relax the whole brain, we produced a set of brain alpha waves. the recording of EEG, alpha waves have a slow rhythm as well as regular and large amplitude (height). with this wave then gradually slows down and we get into a four (4) step, which each show a deeper sleep system than in the beginning:

step. brain waves so small and irregular, dna us so that we are there at the edge of consciousness, sleep easy in the situation. when awakened at this time, we can recall the fantasies or visual images that we see

step 2. our brains sometimes led to a rapid series of short waves as well as having a high wave crest, which is said to be a sleep spindle. problems in the womb tone small, perhaps no longer disturb our sleep.

step 3. in addition to the characteristics of the wave as step 2, our brains sometimes produce delta waves, very slow with a peak high enough. breathing and heart rate slows, muscles went limp and began to difficulty waking.

step 4. delta waves which replaces some of the activities, and we are in a deep sleep. This now takes issue perhaps strong or very loud tone to wake

ongoing series of stages running all 30 to 45 minutes. after which they can move back to the initial step, from step 4 to step 3 to step 2 and then step into. at this point, 70 to 90 minutes after the onset of sleep, a typical thing started to happen. step does not run like a step where we are in the situation woke up and so sleepy, yet brain began to produce a line of long-wave brain moving very fast and irregular. ddaan heart rate increased blood pressure, faster breathing and irregular, face and fingers perhaps there was a seizure. at times in unison, some of the muscles supporting the bones become weak, our brains are actively avoiding bear physical movement. we step into the brakes.

rem sleep is often referred to "paradoxical sleep" because the brain is in a very active condition of the body momentarily inactive though. at this time last clear dreams. bed rest going to set aside some time, until the body can dispose of all waste substances from the muscle, repair cells, power plant or restore, strengthen the immune sstem, or restore lost strength in 1 day.

when we do not get enough sleep, our bodies do not normally work with. parable: reduction of hormones needed for normal muscle changes and benefits the immune sitem (leproult, van Reeth, et al., 1997). on something of a problem, men 51 years experience sleep deprivation. after getting felt very very tired, he was attacked and died of a heart infection. autopsy results show that he has lost almost all of the nerves in two (2) areas of the thalamus associated with sleep and circadian hormonal rhythms (lugaresi et al, 1986)

leproult et al (1997) mentioned that a critical shortage of sleep can increase stress hormone cortisol, which can cause brain cells to damage or interfere needed for evaluation and memory. in addition, some new brain cells can fail to thrive or can be grown with abnormal (guzman-marin et al., 2005). perhaps as a result of the destruction of the disruption of mental flexibility, attention, and creativity. after so many days there are in a situation of constantly awake, generally one can begin to experience hallucinations and delusions (Dement, 1978).

according to the national sleep foundation approximately 10% of some adult critical plagued by insomnia, the trouble continues to be drowsy or asleep. insomnia can last for fear and anxiety, psychological problems, hot flashes during menopause, arthritis, as well as work or study with irregular and in conditions that are too demanding.

Another trigger of daytime sleepiness in the sleep apnea, which is an issue where the system stops breathing momentarily while sleeping, causing the person to choke and shortness of breath, and then woke up shortly.

sleep apnea have most triggers, one of which obstruction of the air line to the failure of the brain to regulate breathing with the fitting, this could lead to someone about natural high blood pressure and an irregular heartbeat.

Narcolepsy is a sleep problem sleepiness shaped attack suddenly and unexpectedly during the day that make someone immediately step into the brakes. narcolepsy is likely due to the reduced benefit of as many nerves in the hypothalamus, which can be caused by a malfunctioning immune or genetic abnormalities (lin, hungs, & mingot, 2001; mieda et al., 2004).

sleep is essential to the consolidation, which is something the system in which the last turn of the synapses that make memories just stored so more durable and stable (sickgold, 1995).
