Section 1 Objective Sleep and Dreams Discuss the four stages of sleep and the period of dreaming.
Define Consciousness: state of awareness, including a persons feeling, sensations, ideas, and perceptions. REM sleep: sleep stage with rapid eye movement, high brain act, deep muscle relaxation, and dreaming. Circadian Rhythm: rhythm of act and impact lasting about 1 day. Insomnia: failure to get enough sleep at night in order to feel rested during the day. Sleep apnea: sleep disorder in which a person has trouble breathing while asleep. Narcolepsy: uncontrolled falling asleep or feelings of sleep during the day. Nightmares: unpleasant dreams. Night Terrors: sleep disruption that occur during stage 4; involve screaming, panic, or confusion. Sleep Walking: walking or carrying out behaviors while asleep.
Describe the following during the levels of sleep. Stage 1 Pulse slows, Muscles relax, Breathing & brain activity become uneven. Can last up to 10 minutes. Production of Theta waves, brain waves shift from low amp & high frequency to high amp and low frequency. Stage 2 Eyes move side to side, and can last up to 30 minutes Stage 3 Large amp Delta waves sweep brain every second or so
