When using the TBSI Wireless Neural Recording System, if you have multiple electrodes near a group of cells, how can you determine how many unique cells from which you are recording?

Often it is the case with multiple electrodes (e.g., ‘tetrode’) bundled close together that some electrodes will predominantly record the same signal, while others may predominantly record current flow generated from other nearby cells. The method used to discriminate between unique cells in this case is referred to as ‘spike sorting’. 
Spike sorting takes into account the temporal and morphological similarities between electrode channels and uses this information to discriminate between different cells. 

Note: LabChart uses a template matching algorithm for spike-sorting within the Spike Histogram Module.
