AP Psych - Unit 1 - Biological Basis of Behavior

consciousness

state of being aware

circadian rhythm

natural internal clock

shift work

employees schedules outisde regular daytime hours

nrem stage 1

drifting in and out

nrem stage 2

light sleep/slow brain waves

nrem stage 3

deepest stage/repair, energize, restore

rem sleep

rapid eye movement, vivid dreams and increased brain activity

rem rebound

increase time spent in rem after sleep deprivation

activation synthesis

dreams are a result of a random burst of neural activity

consolidation theory

dreams are memory consolidation and memory storage/learning from the day

narcolepsy

excessive daytime sleepiness/ sleep attacks

sleep apnea

pauses in breathing during sleep

rem sleep behavior disorder

no longer paralyzed in sleep

somnambulism

sleepwalking

psychoactive drugs

substances that alter brain function

agonists

cause neuro activity

antagonists

blocking effect of neurotransmitter

reuptake inhibitors

block the reabsorbtion of neurotransmitters

stimulants

speed up/ increase neural activity

caffeine

natural stimulant/ increases alertness and fixes tiredness by blocking neurotransmitters

cocaine

stimulant; increases neural activity to cause euphoria, alertness, energy, flood with dopamine

depressants

slow down bodily functions/sedate/relax

alcohol

slows neural activity, impair judgement, coordination, and cognitive functions

hallucinogens

alter perception, mood, and cognitive processes

marijuana

canabis plant, affects how brain recieves messages, alter mood perception and cognition, thc binds to receptors, hallucinogenic affects

opiods

painkilling/sedation

heroin

from morphine, euphoria in pain relief, cascades on neural transmission

tolerance

increasing amount of substance needed to produce same response

withdrawal

symptoms of when you stop using a substance after dependency

addiction

drug seeking, change in brain structure+function, loss of control over consumption
