AP Psychology

Hypothalamus

bodily maintenance (hunger, thirst, body temp.)

Thalamus

sensory switchboard, receives/sends info from sensory neuron

Hippocampus

long term memory, recalling memories/new

Amygdala

controls fear/Aggression (emotion)

Reticular Formation

conciousness/awake/alert, ability to focus

Medulla

controls automatic functions, breathing,heartbeat

Pons

sleep, paralyzes body

Cerebellum

motor control, balance, coordination, voluntary movements

Corpus callosum

connects both hemispheres - communation

Cerebrum

largest part of brain - left and right

Cerebral cortex

high order thinking

Frontal lobe

decision making, planning, Inhibits impulsive behavior

Temporal lobe

auditory hearing, understanding speech

Occipital lobe

vision processing

Parietal lobe

sensory info - touch taste smell etc

Brocas Area

boca - language production

Wernickes Area

comprehension (understanding), speaking but no sense

Left brain

language, reasoning, thinking, control right

Right brain

facial recognition, controls left

Central NS

brain/spinal cord

Peripheral NS

all other nerves

Sensory neurons

takes messages to brain

Motor neurons

messages away from brain towards muscles

Interneurons 

to or away from brain

Somatic

voluntary movements

Autonomic

involuntary movements

Parasympathetic

calm state, conserving energy and reach homeostasis

Sympathetic

fight or flight, higher energy consumption

Pituitary gland

master gland, sends hormones to signal glands to control all others

Thyroid Gland

growth hormones

Pancreas

digestion

Adrenal Glands

blood pressure

EEG

shows brain activity/function - sleep study

CT

shows brain structure - any brain damage

PET

radioactive, measures glucose activity

MRI

detailed structure/blood flow

Brain plasticity

ability to take new functions

Acetylcholine

activate muscles - lower leads Alzheimers

Dopamine

movement, pleasurable activity - higher shizo lower park NO DOPE IN THE PARK

Serotonin

mood, hunger, arousal - high OCD low depression

Nonrepinephrine

fight or flight/alertness

GABA

major inhibitory transmitter, low + tremors,insomnia, seizures

Glumate

excitatory transmitter, high=seizures/migranes

Endorphins

pain/pleasure 

Agonist

opens receptor

Antagonist

blocks neurotransmitter

Resting potential

negative electrical charge, when not fired

Threshold

level of stimulation to trigger

Action potential

message fired - electrical charge

Depolarization

shift in neuron electrical charge

Refractory

brief resting pause

Neurogenesis

formation of new neurons

Dual processing

info processed concious/unconcious
