module 1.4a-1.4c parts of the brain Flashcards
phrenology
studying bumps on the skull
biophysical approach levels of analysis
an integrated approach that incorporated biological, psychological, and social-cultural levels of analysis
neuroplasticity
brain’s ability to change, especially during childhood
lesion
tissue destruction
EEG
recording of waves of electrical brain activity
MEG
brain imaging technique- measures magnetic fields
CT scan
x-rays combined into a representation of a slice of the brain
PET scan
technique for detecting brain activity where a radioactive glucose goes for a task.
MRI
images of soft tissue- done by magnetic fields and radio waves, shows brain anatomy.
fMRI
blood flow and brain activity- brain function and structure
function of hindbrain
breathing, sleeping, arousal, coordination, and balance.
function of midbrain
some movement, seeing and hearing
function of forebrain
complex cognitive activities, sensory and associative functions, and voluntary motor activities
medulla function
heart beat and breathing
pons function
coordinate movements and control sleep
thalamus function
brain’s sensory control center (except smell)
reticular formation function
sensory input from spinal cord and travels through, filters incoming stimuli and relays important info to other brain areas
cerebellum function
motor movement, nonverbal and skill learning
limbic system function
emotions, drives, and memory formation
amygdala function
aggression and fear
hypothalamus function
bodily maintenance, thirst, temp, sexual behavior
hippocampus function
processes conscious, explicit memories
broca’s aphasia
struggle formulating words, but still comprehending speech
wernicke’s aphasia
causes a person to only be able to speak in meaningless words, usually have difficulty understanding people, unaware of their mistakes
frontal lobe
lingusitic processing, muscle movements, higher-order thinking, executive functioning
parietal lobe
sensory input for touch and body position
body map
occipital lobe
visual info
temporal lobe
auditory areas and language processing
fusiform gyrus
recognize faces
neurogenesis
formation of new neurons
lateralization
left and right hemispheres serve different functions
corpus callosum
wide band of axon fibers connecting the two hemispheres and carrying messages
left side of brain controls
right hand, right eye, fouses on language, would say what they saw in the right visual field
right side of brain controls
left hand, left eye, focuses on motor, no speech so patient would point or grab the item
