Examples of µSpikeHunter spike sorting results for spikes recorded from cortical neurons at DIV 15 using the MEA2100-256-System with a sampling rate of 20 kHz and an analysis period of 100 s. (a1) Microchannel B with three source clusters. The boxes on the B9 plot are the ROIs used for sorting. (a2) Intra-cluster averages of the CPV and confidence index for channel B events and the number of events in each cluster. (b1) Microchannel M with two source clusters. The boxes on the M11 plot are the ROIs used for sorting. (b2) Intra-cluster averages of the CPV and confidence index for channel M events and the numbers of events in each cluster.
