TIMS HIGHER CF Flashcards
what is the association cortex? what comprises it?
combines sensory inputs and memory
perception reaction emotion abstract thought communication
what structure is responsible for the communication between the structures?
corpus callosum
advancements made in cortex function?
animal research
neurosurgery
genetic lesions
scanning
what is the association cortex broken into?
parietal/occipital/temporal
prefrontal
limbic
this part of the association cortex is responsible for communication like speech, reading and writing
parietal/occipital/temporal
this part of the association cortex is responsible for motor planning, emotion
prefrontal
this part of the association cortex is responsible for emotion, memory and learning
limbic
test used to assess for cerebral hemisphere dominance?
WADA test
what is the left hemisphere responsible for?
scientific thinking
verbal expression logical thought analytical ability linguistics math
what is the right hemisphere responsible for?
artistic ability
non verbal expression visual/spatial relations synthetic thought initiative music appreciation
term used for regions of the brain that take over the task if the primary region is damaged
eg 1, 2, 3 degree motor cortex, boy who lost a hemisphere in a manure spreader
redundancy
what is the effect of plasticity in recovering brain function?
plasticity
what are the three major groups of disorders of the association cortex?
apraxias, agnosias, aphasias
name this disorder?
inappropriate motor responses
like car keys in ear
damage to premotor cortex
apraxia
name this disorder?
not know, so you incorrectly identify things
agnosia
what sub disorder of agnosia is this?
don’t connect the pieces of the puzzle like friends face, glove and rose
visual agnosia
what sub disorder of agnosia is this?
tactile amnesia, don’t recognize objects by touch
unilateral, non dominant and this is a type of asterognosis agnosia that develops and so you ignore the contralateral half of the body?
astereognosis agnosia
autotopagnosia astereognosis agnosia, if this is in the dominant hemisphere than you ignore the entire body
name this disorder?
disruption of symbolic communication (hearing, speaking, reading and writing) tho there is a connection to reading and speaking
aphasia
what are the two types of aphasia?
brocas (expressive)
wernickes (receptive)
agraphia
Alexia
dyslexia
echolalia
these is what type of cortical disorder?
aphasia
name this aphasic disorder?
can read, but not write
agraphia
name this aphasic disorder?
cannot read
alexia
name this aphasic disorder?
letter/word/symbol reversals and inversions
dyslexia
name this aphasic disorder?
cannot understand what they hear so write the question to communicate with affected
echolalia
what is the syndrome called when the hemispheres do not speak with each other?
disconnection syndrome
