Lec 3 Association Cortices Flashcards
Association cortices receive inputs from…
motor/sensory cortices
thalamus
brainstem
other associatioon cortices
Association corrtices send outputs to…
basal ganglia
cerebellum
thalamus
other association cortices
Parietal lesions result in deficits to…
attention, perception, body awareness
Frontal lesions result in deficits to…
planning/executing normal behavior; significantly alters personality; difficulty matching appropriate behavior to circumstances
Temporal lesions result in deficits to…
recognition & identification (categories of oobjects, faces, etc.)
Contralateral Neglect Syndrome
Parietal lesion.
Complete failure to receive one side of the world (bump into stuff, may fail to dress one half of body, etc.)
Why is RIGHT Contralateral Neglect Syndrome worse than Left?
R parietal controls both R/L sides.
L parietal only controls R (so L lesion = minimal neglect to R).
Contralateral Neglect is most common on which side (R/L)?
Right
Frontal Basilar lesion
memory deficit
Frontal Dorsolateral lesion
indifferent, abulic, apathetic
Frontal Orbitofrontal lesion
impaired judgement, loss of usual social graces
Temporal lesions are collectively called…
Agnosias
Prosopagnosia - what is it
inability to identify/recognize faces
Prosopagnosia usually results from lesions to…
inferior right temporal
Split Brain Studies: objects placed in R hand…
CAN be described accurately.
