Transcranial magnetic brain stimulation (TMS) was used to assess the influence of the corticospinal system on motor output in seven human subjects during a task in which they had to reach out, grasp, and lift an object. Stimuli, directed at the hand area of the motor cortex, were delivered at eight defined points during the task: during reach, at grip closure, during object manipulation, during the parallel isometric increase in grip and load forces, during the lifting movement, and while the… CONTINUE READING
