Real-Time Electroencephalography-Triggered Transcranial Magnetic Stimulation for Cortical Excitation

Source: Stefanou, M., et.al. Brain State-dependent Brain Stimulation with Real-time Electroencephalography-Triggered Transcranial Magnetic Stimulation. J. Vis. Exp. (2019)This video demonstrates the process of real-time EEG-triggered transcranial magnetic stimulation (TMS) to study cortical excitability. The procedure involves positioning the TMS coil over the motor cortex, synchronizing stimulation with specific phases of the EEG signal, and recording motor-evoked potentials (MEPs) to explore the effects of different brain states on cortical responses. This technique allows for precise modulation of brain activity based on real-time EEG analysis.
