Secondary sensory area SII is crucially involved in the preparation of familiar movements compared to movements never made before.

摘要: Secondary sensorimotor regions are involved in integration and movement preparation. These take part parietal-premotor circuitry that is not only active during motor execution but also observation imagery. This activation particularly occurs when observed movements belong to one's own repertoire, consistent with the finding imagery improves performance one can actually make such movement. We aimed investigate whether or of a was never made before causes ability perform this indeed precondition. Nine subjects [group Already Knowing It (AKI)] could abduct their hallux (moving big toe outward). Seven initially failed (Absolute Zero A0 group). They had imagine, observe, execute movement, whereas fMRI data were obtained both after training. Contrasting abduction between AKI-group A0-group showed increased left SII supplementary area activation. Comparing flexion bilateral AKI group. Prolonged training resulted equal similar cerebral patterns two groups. Thereby, conjunction analysis correlations on subject's range execution, imagery, exclusive The reduced involvement may imply effective interplay sensory predictions feedback does place without actual experience.
