Transcranial Magnetic Stimulation (TMS) activates the brain via electromagnetic induction. It is suitable for modulating activity in the cerebral cortex. TMS is a powerful research tool because it allows determining causal relations between brain areas and their functional roles. TMS can be applied with millisecond temporal precision and with a spatial accuracy of ~7-20 mm depending on coil type. TMS can be recorded simultaneously with EEG/EMG, fMRI, and optical recordings.
Our facility is equipped with a Magstim Super Rapid stimulator and a 70-mm figure-of-eight coil, Nexstim eXimia Navigated Brain Stimulation (NBS) frameless neuronavigator, and Nexstim eXimia EEG system comprising 60 EEG and 6 EMG channels. The laboratory is inside a Braden Shielding electrically shielded room. Computer-controlled visual, auditory, and somatosensory stimulation systems as well as behavioral response monitoring are available in the laboratory. Our comprehensive analysis software suite allows integration of TMS, EEG/MEG/EMG, MRI, and fMRI data. The TMS laboratory is located inside the Biomedical Imaging Core (BIC) at the Martinos Center that is equipped to support clinical and pharmacological studies and experiments that require advanced physiological monitoring.
