Induction of continuous high frequency epileptiform discharges or in vitro status epilepticus like activity in cultured hippocampal neurons during exposure to low Mg2+ solution. A. Representative current clamp recording from a control neuron showing occasional spontaneous action potentials. B and C. Representative current clamp recordings showing induction of tonic high frequency epileptiform bursts (in vitro status epilepticus) from neurons subjected to 2 and 8-h of low Mg2+ treatment respectively. Tonic high frequency spiking was observed at all the durations of SE. The results shown were representative of over 20 recordings.
