Comparison of spike train synchronization with and without overlapping spike reallocation. A Examples of spike trains after applying LG, excluding overlapping spikes. The dark vertical lines denote spike. The numeric values on the left represent the spike synchronization index between units enclosed in square brackets. B Examples of spike trains with reassigned decomposed overlapping spikes. The coloured vertical lines denote single units’ spikes decomposed from overlapping spikes. The rest is the same as in A. C The distribution of spike synchronization indices for each pair of units. The shaded blue patch and blue vertical line represents the distribution and median of the synchronization indices between spike trains across repetitions of 500 times, excluding overlapping spikes, after applying LG. The shaded red patch and red vertical line denotes the distribution and median of the synchronization indices between spike trains, reassigning decomposed overlapping spikes, after applying the proposed method. The shaded grey patch and dark vertical line represent the distribution and median of the synchronization indices between actual spike trains of single units. The numeric value at the top of the distribution indicates the absolute difference of the median for each distribution
