  • Abstract
  • Look Inside

When using a tool it becomes an extension of the hand both physically and perceptually―the tool is incorporated into our body image, or body schemata. Although accumulation of psychological evidence indicates body image is modified during tool use, its neural mechanism is entirely unknown as yet. We trained macaque monkeys to retrieve distant objects (beyond the limit of the reach of the innate arm) using a rake as a tool, and neuronal activity was recorded in the anterior bank and the fundus of the intraparietal sulcus contralateral to the hand using a tool.
