Fig 1. Spontaneous hippocampal epileptiform discharges in CA3 and CA1 under nonsynaptic conditions.

Fig 1

(A) Simultaneous recording of synchronous epileptiform activity induced in synaptic blockers aCSF: (1) bursts of discharges, (2) single epileptiform discharges, (3) epileptiform discharges appear simultaneously in CA3 and CA1, while population spikes only in CA1. (B) Nonsynaptic population spikes appear in low-Ca2+ aCSF: (4) epileptiform activity is not synchronized between CA3-CA1 hippocampal zones.
