iintroduction: repetitive transcranial magnetic stimulation (rtms) modulates the excitability of cortical neural networks. the effect of rtms on excitability of cortical networks depends on its frequency. according to the previous reports, a distinction is made between low (<1hz) and high frequencies of rtms. low frequencies of rtms inhibit seizure but high frequencies increase it. in the curre...
