EEG is the sum of excitatory and inhibitory postsynaptic potentials, reflecting the rhythmic activity of neurons in the cerebral cortex, with the good temporal resolution, which can evaluate the dynamic changes of neuronal activity in the brain. Therefore, the combination of TMS and EEG overcomes the limitations of the above methods and studies the changes of neural excitability in the cerebral cortex after TMS stimulation, such as the time-dependent changes in the activation or inhibition of neuronal activity in the cerebral cortex, the duration of the stimulation effect, and the stimulation response. Transmission process in associated brain regions. To further understand the dynamic changes of TMS on brain regulation and the interaction between related brain regions in cognitive activities. In addition, the TMS-EEG method is not affected by subjective consciousness and can objectively evaluate the state of brain activity. Its response characteristics and modulation effects make it suitable for the diagnosis and treatment of clinical diseases.
