Correlation of multiunit discharges with local field potentials within dentate gyrus during the transition period to seizure evoked by kainic acid injection into ipsilateral CA3. A, Six-minute-long record of the transition period and seizure. B, Thirty-second-long record at the beginning of the transition period. B1, Spike-triggered average of 151 field potentials. B2, Autocorrellogram of multiunit discharges. C, A field potential record during the last 30 s of the transition period before the seizure onset. C1, Spike-triggered average of 163 field potentials. C2, Autocorrellogram of multiunit discharges.
