for controlling homeostatic mechanisms?

Definition

 

 

hypothalamus

Term

 

 

Lateral Hypothalamus

Definition

 

 

-drive related behavior

"go"

(ex if hungry this lets you know then you "go"

get food)

Term

 

 

Ventromedial Hypothalamus

Definition

 

 

-satiety

"stop setting"

 

(Ex lets you know when full)

Term

 

 

afferent

Definition

 

 

connections from sensory neurons

(nerves TOWARDS cns)

-bring info TO the brain

 

creates drive

Term

 

 

efferent

Definition

 

 

connections to motor neurons

(nerves LEAVING cns)

-sends info AWAY from brain

 

-tells body what to change

Term

 

 

Olds and Milner Experiment

Definition

-focused on reward pathway

-misplaced electrode (rat would continue to shock itself bc electrode was on reward pathway)

Term

 

 

Another name for the reward pathway

Definition

 

 

Medial Forebrain Bundle

Term

 

 

Structures of the brain found in the 

reward pathway

Definition

 

-lateral hypothalamus

-midbrain

-basal ganglia

Term

 

Stage 0-sleep cycle

Definition

 

-transition from wakefulness

eyes open -β waves

eyes closed -α waves

 

(as appraoches sleep amp↑ freq↓)

Term

 

Stage 1 - sleep cycle

Definition

 

 

-begins sleep (light sleep)

- θ (theta) waves

Term

 

Stage 2 -sleep cycle

Definition

 

Deeper sleep

θ waves

sleep spindles and k-complexes

Term

 

sleep spindles

Definition

 

 

-stage 2

like beta waves (low amp high f)

Term

 

k-complexes

Definition

 

 

-stage 2

-bursts of  ↑amp ↓freq (Δwaves)

Term

 

Stage 3 - sleep cycle

Definition

 

-deeper sleep

-Δ waves (also some θ waves)

Term

 

Stage 4 - sleep cycle

Definition

 

-deepest sleep

- 50-75% Δ waves

Term

 

REM 

Definition

 

-θ wave (awtoothed)

-brain activity similar to awake

(dreaming)

Term

 

Restoration Theory

Definition

 

-time for body to restore and heal

-more strenuous activity = more deep sleep

Term

 

Sleep Apnea

Definition

 

-cant breathe/choke

(either neural or obstructive)

Term

 

Somnambulism

Definition

 

-sleep walking

Term

 

Peripheral Feedback Theory

Definition

(James)

-arousal IS the emotion

-sympathetic response is the emotion

 

stimulus --> perception --> bodily arousal --> emotion

                       (sympathetic response)

Term

 

Cognition Feedback Theory

Definition

(Schatchter and Singer)

 

-although peripheral arousal impt need cognitive interpretation

 

stimulus-->perception-->peripheral response &

                                        cognitive response

Term

 

Cognitive Appraisal

Definition

 

determining which emotion you have

Term

 

Peripheral Arousal

Definition

 

tells you how strong

the emotion is

Term

 

Facial Feedback Theory

Definition

 

-facial expression tells you what mood you're in

 

ex: "e" smiling therefore happier

Term

 

What brain structures play a role in

emotional behavior?

 

Definition

(OAT)

 

-orbital frontal cortex (if damaged sociopath/antisocial)

-amygdala (if damaged - psychic blindness

-cant interpret stimuli)

-thalamus

Term

 

β waves

Definition

 

↓amp ↑freq

-fast and irregular

 

-awake and alert (eyes focused)

(as amp gets higher and freq lower get into 

a deeper sleep)

Term

 

α waves

Definition

 

awake

eyes shut

larger more regular waves

(b/c much activity goes to vision)

Term

 

θ waves

Definition

 

Stage 1 + stage 2 (sleep spindles)

 

↓ amp ↑freq

Term

 

Δ waves

Definition

 

↑amp ↓freq

slow regular waves

Deep sleep

Term

 

Sawtooth θ waves

Definition

 

paradoxical sleep

↓amp ↑freq
