bruh howd i forgot to make flashcards for this

receptive aphasia

damage to Wernickes area

uable to understand sensory input

expressive aphasia

damage to Broca’s area

unable to understand complicated sentences, diffuculy speaking or writing

global aphasia

receptive and expressive

beta rhythm

alert

alpha rhythm

relax with eyes closed

what properties of wave changes when we get sleepy in EEG

waves become lower fequency and larger amplitude

2 phases of sleep

NREM (non-rapid eye movement) N1, N2, N3

REM (rapid eye movement)

Stage N1

NREM: theta waves appear in alpha pattern (light sleep)

Stage N2

NREM

theta waves, sleep spindles, K complexes

Stage N3

NREM (slow wave or deep sleep)

delta waves

how does sleep start

progresson of N1 to N2

paradoxical sleep

in REM because it is hard to wake up

but the EEG avtivity similar to alert/awake (beta)

what happens in REM

paradoxical sleep and dreaming

T or F: each episode of REM gets longer per sleep

true

cycle of sleep

N1, N2, N3, N2, REM, N2

what does sleep deprivation do

impair immune

causes cognitive and memory deficits

leads to psychosis and death

2 types of emotion

internal attitude toward environment (happy/sad)

external responses (emotional behaviour)

primary motivated behaviour

directly related to homeostasis

secondary motivated behaviour

pleasure or addictive behaviours

reward and punishment are ____ from motivation

inseparable

mesolimbic and mesocortical dopamine paths

part of reticular activating system involving motivation, reward and punishment

how do mesolimbic and mesocortical dopamine pathways work

begin in midbrain and release dopamine to areas that process information

forebrain structures in emotional response

cerebral cortex

modulate, direct, interpret, and inhibit emotional behaviours

limbic areas in emotional responses

inner emotions

amygdala

lateral hypothalamus in emotionla responses

aggressive and defensive behaviours including rage
