title: Altered seizure susceptibility after high-frequency transcranial magnetic stimulation in rats.
abstract: The long-term effect of repetitive transcranial magnetic stimulation (rTMS) on the susceptibility of amygdala kindling was studied. Two weeks after a single high-frequency rTMS train (120 A/micros, 20 Hz for 3 s), the rats had a 55% higher threshold for induction of epileptic afterdischarges compared with sham-treated or control rats. However, subsequent kindling revealed no difference between rTMS-treated and control rats. Our data suggest that a single rTMS train has long-term effects on the neuronal excitability. These effects may be anticonvulsant and therefore support the safety of rTMS in clinical use.
