| Abstract(in English) | Human movement control has been suggested to use predictive control of self-movement, based on both motor commands and sensory feedback. This study investigated the neural basis for predictive control of human movements. Participants were instructed to trace visually presented curves, and an artificial delay was introduced to visual feedback. Brain activities during movement were measured using fMRI. Analysis of motor errors and brain activity revealed significant positive correlations between activity at the temporoparietal junction (TPJ) and motor performance under delayed visual feedback conditions. Furthermore, activity of the posterior parietal cortex (PPC) was greater when motor errors of the subject were presented visually. These results suggest that the PPC plays significant roles in calculating visuomotor prediction errors, while the TPJ is involved in state estimation of self-movement during visually guided movements. |
