Combining transcranial stimulation with other brain imaging techniques to trace human brain function
In my talk, I will highlight how transcranial magnetic stimulation (TMS) can be combined with various neuroimaging techniques to investigate the functional neuroanatomy of human motor control. In a first series of experiments, we applied focal TMS over the dorsal premotor cortex (PMd) during visually cued movement selection and “online” neuroimaging was used to map how focal cortex stimulation acutely modified neural activity and connectivity in the stimulated neuronal circuits. In a second series of experiments, repetitive TMS (rTMS) was applied to the PMd to induce rapid reorganization in the functional brain networks subserving visually cued action selection. The temporospatial patterns of TMS-induced reorganization were subsequently mapped using “offline” neuroimaging.
