Somatosensory-motor cortex interactions measured using dual-site transcranial magnetic stimulation

Dual-site transcranial magnetic stimulation (ds-TMS) is a neurophysiological technique to measure functional connectivity between cortical areas.To date, no study has used ds-TMS to investigate short intra-hemispheric interactions between the somatosensory areas and primary motor cortex (M1).We examined somatosensory-M1 interactions in the left hemisphere in six experiments using ds-TMS. In Experiment 1 (n = 16), the effects of different...
