Measurements of the K activity (aiK) in ferret ventricle were made using either single- or double-barrelled K-sensitive micro-electrodes. aiK was also estimated from the Nernst equation by measuring the membrane potential when changing the external K concentration. Micro-electrodes filled with

Local neocortical and hippocampal territories show different and sterotypical patterns of acutely evolving, epileptiform activity. Neocortical and entorhinal networks show tonic-clonic-like events, but the main hippocampal territories do not, unless it is relayed from the other areas. Transitions in the
