apraxia
lesion to primary sensory area means
poor localization of sensory stimuli
lesion to sensory association area means
tactical agnosia (can’t interpret significant of sensory info)
taste comes from
insula (gustatory)
parietal association area
attention
self awareness
awareness of personal space
temporal association area

medial temporal lobe
know faces
frontal association area
direct/maintain attention problem solving calm planning regulate emotion expression
broca aphasia
motor aphasia (expression) not fluent
wernike aphasia
sensory aphasia
not comprehending, non sense
conduction aphasia
can’t repeat words
comprehension / production is ok
thalamus
gate keeper for cortex
prioritizes info
neuroplasticty
observable change neuron structure / function
measuring neuroplasticity
individual neurons and population of neurons
facilitators of brain plasticity
redundancy
unmasking
distributed processes
dynamic connectivity
redundancy
more than one brain area can support the function (write w toes)
unmasking
neurons are silent until injury
distributed processes
functions not localized in one area
dynamic connectivity
form new connection
what can induce plasticity
hormones drugs disease injury experience
principals of experience dependent plasticity
use it or lose it use it and improve it specific repetion intensity
