Posterior parietal cortex

Damage to the posterior parietal cortex can produce a variety of sensorimotor deficits, including deficits in the perception and memory of spatial relationships, inaccurate reaching and grasping, in the control of eye movement, and inattention.

[3][5] The posterior parietal cortex has been understood to have separate representations for different motor effectors (e.g. arm vs.

[10] Posterior parietal cortex appears to be involved in learning motor skills.

[11] Learning a brain-computer interface produces a similar pattern: posterior parietal cortex activation decreased as subjects became more proficient.

[13] In a study conducted by neuroscientists at New York University, coherent patterns of firing of neurons in the brain's PPC were associated with coordination of different effectors.

[14] In addition, neurons in posterior parietal cortex encode various aspects of the planned action simultaneously.

[16] Maintaining spatial attention depends on the right posterior parietal cortex; lesions in a region between the intraparietal sulcus and inferior parietal lobule in right PPC were significantly associated with deficits in sustained spatial attention.

[3][4] Damage to posterior parietal cortex results in deficits in visual working memory.
