Title: Changes in network connectivity induced by TMS stimulation of DLPFC: a concurrent fMRI-EEG-TMS study. Session: Oral Session Speaker: Hengda He Abstract: TMS over the left dorsolateral prefrontal cortex (L-DLPFC) is an FDA-approved treatment for depression. However, the effects on networks distal to the stimulation site are less understood. Previous studies have shown that TMS applied to the DLPFC attenuates hyperactivity in the default mode network (DMN)[1], though its effects appear to be highly heterogenous, with reports of such stimulation both increasing and decreasing neuronal activity, depending on the region, network and stimulation parameters[2]. Here, we aim to investigate the network-level effects of TMS, by assessing how application of TMS at L-DLPFC propagates through cortical networks and induces changes in whole-brain network functional connectivity (FC).
