Coding of modified body schema during tool use by macaque postcentral neurones

摘要: A tool is an extension of the hand in both a physical and perceptual sense. The presence body schemata has been postulated as basis assimilation hand. We trained macaque monkeys to retrieve distant objects using rake, neuronal activity was recorded caudal postcentral gyrus where somatosensory visual signals converge. There we found large number bimodal neurones which appeared code schema During use, their receptive fields were altered include entire length rake or cover expanded accessible space. These findings may represent neural correlates modified incorporated.
