Document Summary
Parietal cortex processes and integrates somatosensory and visual information, with regard to control of movement. Anatomy lies between the frontal and occipital lobes roughly demarcated anteriorly by the central fissure, ventrally by the lateral fissure, dorsally by the cingulate gyrus, and posteriorly by the parietal-occipital sulcus. Inferior parietal lobe: supramarginal gyrus and angular gyrus. parietal lobe can be divided into 2 functional zones: anterior zone: somatosensory cortex, posterior zone: posterior parietal cortex. pg (parietal area g) has visual function and is larger in humans (especially in the rh). specific parietal-lobe regions take part in dorsal stream of visual processing: cips = intraparietal sucus control in saccadic eye movements (area l ip) and visual control of object-directed grasping (aip, prr = parietal reach regions. Saccade is a series of involuntary, abrupt and rapid small movements or jerks made by both eyes simultaneously changing the point of fixation.
