Research Abstract

We delivered suprathreshold TMS to left M1 or gave electrical right median nerve stimulation in healthy volunteers while simultaneously conducting fMRI and monitoring with EMG. We examined in detail the localization of TMS-, muscle afferent- and superficial afferent-induced activity in M1 subdivisions. Muscle afferent-and TMS-evoked activity occurred mainly in rostral M1, while superficial afferents generated a slightly different activation distribution. This result was almost consistent with the previous study in squirrel monkeys (Strick & Preston, 1982). The present study appears to justify the use of fMRI combined with suprathreshold TMS to M1 for evoked motor network imaging.
Next, we developed a novel MRI scanning technique which enables us to measure neuronal activity in the brain and the spinal cord simultaneously. Using this technique, to our knowledge, we first demonstrated a cerebrospinal functional coupling during motor tasks in human, noninvasively.
