nothing is wrong but you lose movement---ideomotor, constructional

associative agnosia

describe, not name

image generation occurs in

L hemisphere

parietal lobe ventrally marked by

sylvian fissure

supramarginal/angular gyrus demarks

inferior parietal

parietal cortex and prefrontal cortex function

spatially guided behavior

posterior parietal damage causes inability to

reach toward visual target

sensory feedback actual outcome intended movement is

efference

spatial navigation

mental transformations

organize gray matter in anterior parietal

math, mentally rotating and manipulating objects

mental space in posterior parietal

posterior to central sulcus function

processing somatosensory info

pari stroke-reports R touch when L touch

allesthesia

1 object at a time, misreach--disease

Ballint's

R parietal lesions-what neglect

unilateral neglect

hemispatial neglect causes

impaired attention to personal space
