Figure 1. Focal seizure recorded under ketamine-xylazine anesthesia.

Figure 1

a. Simultaneous quadruple intracellular and one local field potential (LFP) recordings performed in the suprasylvian gyrus of a cat anesthetized with ketamine-xylazine. The position of each recording location is indicated in the inset. Note that the seizure is recorded in the two anterior intracellular recordings as well as in the LFP recording, but not in the two most posterior intracellular recordings. The seizure is composed of fast runs (b) and polyspike-wave (c) that remain located in the anterior region of the suprasylvian gyrus. d. Zoom-in on the LFP and one posterior intracellular recording shown in (b) showing that posterior recordings receive EPSPs with the frequency of anterior fast runs but they are not contributing to the seizure.
