39 Cards in this Set

  • Front
  • Back
experiments used to measure aggression
1. Isolation-Induced agression
2. Pain-elicited agression
3. Muricide (mouse murder)
Limbic system
(alter emotions: assoc. w/these sytems)
- amygdala
- hippocamp
- olfactory tract
- cingulate cortex
Kluver Bucy
damage to limbic system (amyg), hippo & anterior temporal lobe

result in loss of fear, hypersexuality, etc)
Papez circuit
cingulate cortex → hippo → hypoth → anterior cortex of thal → cing. cort

how emotion reaches consciousness
movie: pesticides
man killed w.

chem exposure → firing AP → ACh release → no cholinesterase
carbaryl
cholinesterase inhibitor

insecticide
progesterone
treatment to ↓ aggressioin
hippocampus
species-specific behav, memory, navigation

vulnerable to: stress
amygdala
emotional & species typical behav

multimodal
frontal lobe main regions
1. motor cortex
2. premotor cortex
3. prefrontal cortex
(dorsolateral & inferior)
dorsolateral prefrontal cortex
influece movement & memory

send connections to posterior parietal cortex
inferior prefrontal cortex
influence autonomic sys (BP, respiration)

send connect. to amyg & hypo
expressed emotion
Δ in heart rate, BP, hormone secretion
forms of experience
1. autonomic - hypoth
2. subjective - amyg, front lobes
3. cognitions - cortical
James-Lange Theory
brain create story to explain autonomic reactions
somatic marker hypothesis
emotions & feelings guide behav. & decision making

- unconscious process
frontal leukotomy
leukotome inserted bone of eye.

Inferior frontal cortex disconn. from brain

no emotion
addiction
phys. dependence & abuse, tolerance & w/drawl
psychomotor activation
↑ behav & cog ability
DA & drug use
1. DA somehow rewarding
2. abused drugs release DA
3. drugs ↓ DA NOT abused
explaining drug abuse
1. pleasure due to drugs
2. pleasure linded by assoc learnning (cues)
3. incentive salience (highly desired)
incentive-sentizatioin theory
wanting & liking theory
(craving & pleasure)

explanation to drug abuse
disinhibition theory
selective depressant effect on cortex (judgement), not on subcor (instincts)
alcohol myopia
immed. cues - prominent
remote cues - ignored
genetic contribution to drug abuse
1. twins
2. parent influence
3. breeding
Domoic Acid Mystery
- similar to glutamate
- agonist
- binds to kainate receptor
(influx Ca, "suicide gene" postsynaptic neuron)
hormones
chems from endocrine gland
endocrine gland
cell grps in body, secrete hormones
hormone classifications
- steroid hormone: fat-soluble chem mess. from cholesterol
(↓ & ↑ production of proteins)

- peptide hormone: affect target cells physiology
behavioral functions of hormones
1. homeostasis
2. gonadal hormones
3. fight-flight
(glucocorticoids)
Symptoms of drug addiction
1. need to continue consuming
2. ↑ dose (tolerance)
3. dependency
induce drive state
use to manipulate behave
behav of addicts
1. lack interest
2. unmotivated
3. pleasure limited
4. don't avoid bad
external cues
play role in maintaining addictive behav
methadone
similar high as morphine

-w/drawl longer lasting
nucleus acumens
pleasure center

- key in DA center
- if destroyed...stop self admin of drug
cocaine
stim primitive behav
morphine
shut down higher cortex, primative take over
alcohol
inheritability deficits

- P3 is the λ missing
