Parietal Lobes Flashcards
(36 cards)
areas 1, 2, and 3 is?
Anterior Parietal Cortex
area that receives connections from primary somatosensory cortex and sends outputs to primary motor and supplementary motor and premotor. Plays role in guiding movements by providing info regarding limb position.
Area PE
3 categories of spatial processing
body centered space, egocentric space, and allocentric space
within this domain we can identify the sense of the body surface as a three dimensional space.
Body centered space
Refers to the perception of spatial location outside the body but with reference to it.
egocentric space
refers to representations of space that is independent of the observer, of body centered space
Allocentric space
two systems for object recognition and spatial processing
