Favorable Recording Criteria for Spike Sorting
... At complete overlap, spikes having identical waveforms, even when they have different amplitudes, will be perfectly correlated and all constellation points will lie on the horizontal axis. If the waveforms differ, being aligned in time still produces the maximal correlation, but it is not one. The r ...
