| Research Abstract |
A mechanism that monitors the congruence between sensory inputs and motor outputs is necessary to control voluntary movement. The purpose of the present study was to elucidate the neural mechanisms in detecting incongruence if visual feedback did not match with the predicted one based on somatosensory feedback and motor command. The results showed activity in the primary somatosensory area to be inhibited and activity in the secondary somatosensory area (SII) to be enhanced with voluntary movement, and neural responses in the SII and parietal cortex were strongly affected by the unexpected visual feedback. The integration among the visual, somatosensory information and motor command plays a crucial role in the feeling of agency. These results provide evidence that a mechanism that monitors sensory inputs and motor outputs congruent with current intension is necessary to control voluntary movement.
