Multimodal Neural Recording: fMRI-EEG-TMS (fET) System

We developed a functional magnetic resonance imaging (fMRI)-electroencephalogram (EEG)-transcranial magnetic stimulation (TMS) instrument (fET instrument) capable of acquiring simultaneous fMRI and EEG during noninvasive single pulse TMS. We used this instrument to apply single-pulse TMS to the left DLPFC and test whether prefrontal EEG alpha phase moderates TMS-evoked top-down influences on subgenual, rostral and dorsal ACC.
