explain the sleep wake cycle
Circadian rythm(biological rythym that takes place every 24 hrs) we sleep at night time and are awake during the day. Hypothalamus contains biological clock of the body. Pineal gland releases melatonin which helps us sleep.
Mention the different NREM stages. (brain waves, muscle tone, eye movements)
Stage 1: we drift off to sleep. slowdown in rate of respiration and heartbeat. Also decrease in muscle tension and body temp. Alpha and theta waves.
Stage 2:Body goes into deep relaxation. sleep spindles.
Stage 3 and 4: Deep sleep. Delta waves. heart rate and respiration slow.
What occurs during REM sleep. (brain waves, muscle tone, eye movements)
Dreaming occurs in REM sleep. there are rapid eye movements. high brain activity but no movement.
What are some sleep phenomena(parasomnias)?
-Sleep walking and talking: often have eyes opens. occurs during slow sleep waves.
-night terrors: occurs during NREM sleep. sense of panic along with screams.
What are some sleep disorders?
-Insomnia: constant difficulty to go to sleep or stay asleep.
-Narcolepsy: Random daytime sleep attacks
-Sleep apnea: repeated awakening after breathing stops.
Compare the evolutionary and cognitive theories of why we sleep?
-Evolutionary theory:we need sleep in order to function. we sleep in safe places to reduce chance of harm
-Cognitive theory:sleep is important for our memory and function formation
What are the effects of sleep deprivation?

What are clinical uses for stimulants?
anesthetic, ADHD, narcolepsy treatment
What are examples of depressants?
Alchohol, opiates like opium, morphine, heroin, codeine.
What do depressants do?
reduce neural activity and other bodily functions.
creates feelings of disinhibition(GABA,Glutamate and dopamine NTs). Blocks excitement. Clinical uses:painkillers.
What is the active ingredient in Marijuana?
Effects of Marijuana
Relaxation;enhanced sensation; altered cognition.
Memory and motor impairment.
What does marijuana mimic?
endocannabnoids(Anadamid) which increases dopamine but decreases GABA/glutamate
