Posterior parietal cortex

Posterior parietal cortex located between the the visual cortex. The main function of this part of brain is planned movement, attention, and spatial reasoning.

Parietal cortex responsible for many action and damage in the posterior parietal cortex can cause various type of sensorimotor deficit, including inaccurate grasping and reaching to an object, spatial relationships, control of eye movements and inattention. The two main consequences of damage in PPC is hemispatial neglecte and apraxia.
