Regenerative, AlI-or-None, Electrographic Seizures in the Rat Hippocampal Slice in Physiological Magnesium Medium

  • Conference paper
Synaptic Plasticity in the Hippocampus

Abstract

Previous studies have shown that electrographic seizures (EGSs) can occur spontaneously for several hours in the hippocampal slice in Mg-free medium containing the GABAb agonist baclofen. We report here that similar all-or-none EGSs could be triggered in physiological Mg medium (with or without baclofen) if the EGSs were induced by several stimulus trains, and sometimes transiently exposed to Mg-free medium.
