PS365 Chapter 14: PS365 Chapter 14 The Parietal Lobes
Document Summary
In pg, polymodal cells respond to somatosensory and visual inputs (polymodal: also asymmetrical (larger in right hemisphere of humans) Lip saccadic eye movements: aip visual control of object-directed grasping, parietal reach regions (prr) role in visually guided grasping movements. A theory of parietal-lobe function: anterior (somatosensory) parietal zone, processes somatic sensations and perceptions, posterior (spatial) parietal zone. It"s likely to be a series of neural representations of space that vary in 2 ways: different representations serve different behavioural needs, spatial representations vary from simple (control simple movements) to abstract. Behavioural uses of spatial information: direct actions at object in the world, and assign meaning/significance to them, can think of spatial recognition as similar to form recognition, object recognition, movement guidance. Parietal neural activity: human use, an array of electrodes can be implanted over prr, and the recorded activity can be used to move a mechanical device.
