Abstract

THE role of the primary motor cortex (M1) during mental simulation ofmovement is open to debate. In the present study, functional magneticresonance imaging (fMRI) signals were measured in normal right-handedsubjects during actual and mental execution of a finger-to-thumb opposition task with either the right or the left hand, There were no significant differences between the two hands with either execution or simulation. A significant involvement of contralateral M1 (30% of the activity found during execution) was detected in four of six subjects. Premotor cortex (PM) and the rostral part of the posterior SMA were activated bilaterally during motor imagery. These findings support the hypothesis that motor imagery involves virtually all stages of motor control.
