A spilt in consciousness, which allows some thoughts and behaviors to occur simultaneously with others
Circadian Rhythm
The biological clock; regular bodily rhythms (example: of temp and wakefulness) that occur in the 24 hour cycle.
REM Sleep
Rapid eye movement sleep; A recurring sleep stage during which vivid dreams commonly occur. Also known as paradoxical sleep, because the muscles are relaxed (except small twitching) but other body systems are active
Alpha Waves
The relatively slow brain waves of a relaxed, awake state
Sleep
Periodic, natural loss it consciousness- as distinct from unconsciousness resulting from a come, general anesthesia, or hibernation
Hallucinations
False sensory experiences, such as seeing something in the absence or an external visual stimulus
Delta Waves
The large, slow brain waves associated with deep sleep
NREM Sleep
Non-rapid eye movement sleep; encompasses all sleep stages except for REM Sleep
Suprachiasmatic Nucleus (SCN)
A pair of cell clusters in the hypothalamus that controls circadian rhythm. In response to light, the SCN causes the pineal gland to adjust melatonin production, thus modifying our feelings of sleepiness.
Insomnia
Recurring problems in falling or staying asleep
Narcolepsy
A sleep disorder characterized by uncontrollable sleep attacks. The sufferer may lapse directly into REM sleep, often at inopportune times.
Sleep Apnea
