Spontaneous firing patterns recorded in wild type, connexin 45 ko and connexin 36/45 dko retinal ganglion cells using a multielectrode array. For each movie, dots represent the positions of electrodes in the multielectrode array on which discrete units were recorded. Electrode spacing is 100 microns. The diameter of each dot represents the average firing rate recorded over 500 ms on that electrode. The movies play five times as fast as real time, and each represents five minutes of recording. Only electrodes in which unambiguous units could be isolated from each other are illustrated. If multiple units were recorded on the same electrode, units were randomly displaced around the center so all are visible with minimal overlap.
