How Important Is Spike Sorting?

How Important Is Spike Sorting? on Simons Foundation

By Grace Lindsay July 1, 2019 Many experiments in systems neuroscience follow the same general steps: Record neural activity using a multielectrode array, sort the activity on each electrode as coming from different individual neurons, and use the activity of the neural population to understand behavior. New research published in Neuron in June asked just how important the second step — known as “spike sorting” — really is. (For more on spike sorting, see “ Spike Sorting Becomes Fully Automated .”) Spike-sorted and unsorted activity produces similar neural trajectories, low-dimensional descrip
