Figure 9.

Cluster homogeneity of delay maps from Cat 1. Delay maps from 25 detected spikes closest to their respective cluster centers (L1 distance) are depicted for three different clusters within the Cat 1 data set. The colors represent the relative delay of the spike peak for each detected spike with voltage amplitudes large enough to cross the detection threshold. Blue indicates an electrode with an early detection and red indicates an electrode with a late detection. The deep blue of the background represents the electrodes whose voltage spike amplitudes were not large enough to cross the voltage threshold.
