(A) Sharp-wave-ripples occur during quiet wakefulness and sleep [upper two EEG channels right [after (7)]. (B) Comparison of sharp waves (SPW) and interictal epileptic discharges (IEDs) in the intact hippocampus and after disconnection from its subcortical connections by fimbria-fornix lesion. Channels (1–7) represent different locations along the axis of the hippocampus. See tighter synchrony of population bursts and larger amplitude of the field responses during IEDs]. The shallow line shows the field potentials parallel with the unit discharges [After (7)]. (C1) Human MTLE spike and coupled ripple (32). (C2) Bragin et al. (33) in rats ().
