Abstract

Open-loop therapeutic non-invasive brain stimulation (TMS, tDCS) has been employed for more than two decades, but success is still limited by low effect size and high inter-subject variability. Using real-time analysis of EEG data, we have demonstrated that coupling TMS with specific brain states such as the trough or peak of the µ-rhythm in sensorimotor cortex reveals states of high- versus low-excitability of the corticospinal system, respectively. Applying  repetitive TMS consistently to the high-excitability but not low-excitability state results in long-term potentiation (LTP)-like plasticity of the corticospinal system, with significantly less inter-subject variability compared to open-loop protocols. A first pilot trial in treatment-resistant major depression disorder (MDD) demonstrated that brain-state-dependent repetitive TMS, targeting the trough of the theta rhythm over dorso-lateral prefrontal cortex, resulted in significant reduction of alpha-power, a MDD disease marker, while this was not the case in open-loop repetitive TMS control conditions. The lecture will take the outlook that therapeutic brain stimulation will soon face a paradigm-shift from open-loop to closed-loop approaches.
