Modeling TMS-induced Cortical Network Activity

Uni-focal TMS (MagVenture, Farum, Denmark) is delivered to one brain area while EEG/EMG (NeurOne, Bittium, Kuopio, Finland) are recorded. The targeted brain areas and TMS intensities may vary across runs. An MRI-based TMS navigation system (Localite, Bonn, Germany) is used to navigate the TMS coil.

During each PAS run, bi-focal TMS (MagVenture, Farum, Denmark) is delivered to two brain areas while EEG/EMG (NeurOne, Bittium, Kuopio, Finland) are recorded. The asynchronies between the two TMS coils are kept constant within each session but differ across sessions. Within each session, to observe PAS effects on connectivity, uni-focal spTMS is delivered to the stimulated areas before and after the PAS modulation while EEG/EMG (NeurOne, Bittium, Kuopio, Finland) are recorded. In addition, resting-state EEG/EMG and a behavioral measure (bimanual task coordination) are recorded before and after the PAS modulation. An MRI-based TMS navigation system (Localite, Bonn, Germany) is used to navigate the TMS coils.
