Fig 9. Responses detected by only one spike sorting algorithm.

Fig 9

Displayed are five different visual stimuli, and corresponding neuronal responses. Each row (A–E) shows the visual stimulus presented and two raster plots. The raster plots on the left correspond to a unit in the Combinato sorting, and the raster plots on the right correspond to a unit in the WaveClus sorting, on the same channel. Differences in spike sorting become apparent. A Combinato generated a sparse unit that enabled detection of the neuronal response. The unit generated by manual operators of WaveClus was not detected as a response. B, C Tiny differences in the units’ composition led to a large difference in the numeric response score. D The unit generated by Combinato violates the requirement that one spike has to be fired during at least four picture presentations. E Differences in unit composition led to a large difference in the numeric response score. S, numeric score of the response; R, rating given to the response by human raters. Stimulus pictures displayed here have been replaced by similar pictures for legal and privacy reasons.
