brain stuff

AP psych

Reticular formation

a nerve network TRAVELING through the brainstem into the thalamus and plays an important role in controlling attention in AROUSAL and ALERTNESS

Medulla

in charge of breathing and HEART BEAT (med-dul-la = ba-du-bump)

PONs

connects cerebellum and brainstem and movement/sleep

cerebellum

B A L A N C E and coordination, judgment. WHEN DRUNK ITS AFFECTED!!!

thalamus (touching the llamas)

receives SENSORY information, directs messages to cerebellum and medulla

limbic system (EMOTIONS)

emotional drives with amygdala, hippocampus and hypothalamus

amygdala

ANGRY AGGRESSION

hippocampus

camping memories of facts and events

HYPO-thalamus

directs maintenance like eating drinking body temp and pituitary gland (emotion/reward)

corpus callosum —> split brain

fibers connecting the hemispheres together, severing it can treat epilepsy

cerebral cortex

ULTIMATE CORTEX, information processing and perceptual awareness/thinking/speaking/consciousness

front of the head —> FRONTAL LOBE

prefrontal cortex lives here has broca’s area and motor movements and controls judgment and decisions/personalities.

norepinephrine

a neurotrasnmitter in charge of AROUSAL AND ALRETNESS

occiptial lobes

visual fields of opposite eyes for processing

temoporal lobes / auditory cortex

EARS, auditory areas, has wernicke’s area for language comprehension

parietal lobe

pari painful (vary painful) in charge of pain pressure and temp and has SOMATOSENSORY CORTEX

somatosensory cortex

specified area of the lobe that takes in sensory input

electroencephalogram (EEG)

electrodes on scalp to measure electrical neuron activity

functional ,magnetic resonance imagine (FMRI)

measures blood flow to brain regions by comparing multiple MRI scans

Brain LE-sONs

deliberatley removing parts of brain to see effect, done with rats usually

left eye controls _____ hand and processed in ______ side of brain

right eye controls ____ hand and processed on _____ side of brain

right hand and left side of brain (broca area association with speech on left side)

neuroplasticity

brains ability to change and reorganize after damage/experience.

neurogenesis

ability to produce new neurons

removing ______ will cause you to become extremely hungry and thirsty all the time

hypothalamus (hypos are hype to eat)

even though he felt safe his heart rate would not calm down, his eyes were big and food no digest. what failed him?

Parasympathetic nervous system : which control's the body's fight or flight response and ability to relax

she realized she damaged her ______ neurons because she was bleeding but couldn’t feel anything

sensory

she couldn't feel anything her ______ were damaged

somatosensory cortex
