Low-frequency stimulation (LFS) has been considered as a new option for the treatment of intractable epilepsy. The present study was designed to determine whether LFS of the kindling focus given at different time points after seizures exert different roles on kindling seizures. Our results showed that: (i) In kindling animals, LFS delivered immediately after cessation of the kindling stimulus inhibited the seizure stage during kindling acquisition, whereas LFS delivered after the cessation of afterdischarge accelerated the kindling progression to stages 1 and 2. (ii) In fully kindled animals, when using the generalized seizure threshold current as the kindling stimulus, immediate LFS decreased the incidence of generalized seizures and the average seizure stage as well as shortened the cumulative generalized seizure duration (GSD). However, delayed LFS prolonged the cumulative GSD and afterdischarge duration. Our …
