(A) Seizure severity comparison between single high dose (SHD) and repeated low dose (RLD) of KA in mice during SE. Animals in RLD group showed more severe seizures and spent more time in ≥3 stage when compared to the SHD group during the 3 h of SE. Animals in both groups were given 20–30 mg/kg kainate (i.p.) (***p < 0.0001, two-way ANOVA between 1 and 719 degrees of freedom, F = 148.60, n = 30 for each group). Adopted and modified from Tse et al. (2). (B–E) An example of a 30-min EEG trace, during SE, showing inter-ictal activity that comprises of continuous epileptiform spikes and seizure cluster <12 s without any behavioral phenotype. Convulsive seizures (CS) and non-convulsive seizures (NCS) were observed throughout SE, but behavior activity was evident only during CS, i.e., stage ≥3. Expanded electroencephalography (EEG) traces of (B) are shown in panels (C–E).
