High frequency. According to the popular health website, high-frequency stimulation can effectively excite or inhibit the function of cerebral cortex, thus achieving therapeutic effect. Transcranial magnetic stimulation can precisely regulate the cerebral cortex by changing the pulse frequency. The stimulation depth and range of transcranial magnetic low frequency is limited, which can only affect the local area of cerebral cortex and has little effect on the deep brain structure, so transcranial magnetic high frequency is good.
