Matching of laboratory burst clusters to outdoor recordings.

<p>Clusters of bursts from laboratory recordings (black), matched to clusters of bursts from outdoor recordings (red). Four examples of matched clusters (in response to stimulus classes 4 (top left), 3 (top right), and 1 (bottom left and right) are shown. For these laboratory clusters, closely matching clusters are found in the outdoor recordings. <i>D</i> defines the distance between the exemplars of the two matched clusters under the spike-time metric. As a comparison, the numbers in parentheses give the average distances between Poisson spike trains with identical time-varying firing rate profiles.
