cerebral cortex Flashcards
frontal lobe
right behind your forehead
function: memory, decision-making, problem-solving, planning
damage: become impulsive, irritable, aggressive, withdrawn, difficulty judging what’s socially acceptable
parts of the frontal lobe and what they do
prefrontal cortex: personality expression
promotor and primary motor: control voluntary muscle movement
parietal lobe
back, top of head
function: process sensory information, controls voluntary movement
damage to left: confusion between left and right, difficulty reading and writing
damage to right: problems with self care and making things
parts of the parietal lobe
somatosensory: the ability to sense/touch things
primary taste: taste
occipital lobe
function: interpretation of color, taste, distance, visual, motion detection
damage: problems with vision, identifying color, inability to identify objects
temporal lobe
your temples, side of head
function: organize what we see, hear, language, and memory. speech production
damage: difficulty recognizing faces, speech, short term memory loss, altered personality
cerebellum
lower back part of the skull
function: balance, muscle tone,
damage: loss of coordination, tremors, dizziness, studied speech, weak muscles
brain stem
where your spine and skull meet
function: breathing, heart rate, swallowing, sweat, blood pressure, digestion, body temp, sleep, balance
damage: difficulty swallowing, balancing, insomnia, dizziness
parts of the brain stem
thalamus: sensory control center, top of the brain stem
reticular formation: controls arousal
pons: coordinate movement and sleep
medulla: base, it controls heart rate and breathing
hippocampus
helps process explicit memories for storage.
hypothalamus
directs eating, drinking, body temperature; helps govern the endocrine system via the pituitary gland, and is linked to emotion and reward
amygdala
involved in memory and emotion, particularly fear and aggression.
Electroencephalogram (EEG)
Electrodes placed on the scalp measure electrical activity in neurons.
Magnetoencephalography (MEG)
A head coil records magnetic fields from the brain’s natural electrical currents.
Computed tomography (CT)
X-rays of the head generate images that may locate brain damage.
