A) Clusters for the aggregated bursts of two omega-cell preparations recorded simultaneously in their natural habitat; no broadcast of artificial stimuli. Bursts from preparation 1 are drawn in red, and bursts from preparation 2 in black. Every cluster contains about half of its bursts from one preparation. B) Spike-time distance of the most similar burst in the same preparation in comparison to the most similar burst in the other preparation. The clustering of points around the diagonal shows that for every burst in one preparation the distance of the closest match in the same and in the other preparation are almost identical. C) Similarity of spiking times within bursts. For every spike at time t in a burst in one preparation we compute for different time windows how often there is a spike within a burst in the other preparation in the time window . We find that of all spikes have a corresponding spike in the other preparation within a 5 ms time window, and within a 10 ms time window.
