Fast and accurate spike sorting of high-channel count probes with KiloSort
New silicon technology is enabling large-scale electrophysiological recordings in vivo from hundreds to thousands of channels. Interpreting these recordings requires scalable and accurate automated methods for spike sorting, which should minimize the time required for manual curation of the results. Here we introduce KiloSort, a new integrated spike sorting framework that uses template matching...
متن کاملAutomatic Spike Sorting Using Tuning Information
Current spike sorting methods focus on clustering neurons' characteristic spike waveforms. The resulting spike-sorted data are typically used to estimate how covariates of interest modulate the firing rates of neurons. However, when these covariates do modulate the firing rates, they provide information about spikes' identities, which thus far have been ignored for the purpose of spike sorting....
متن کاملA Brief Look into Spike Sorting Methods
Spike sorting is a class of techniques used in the analysis of electrophysiological data. Studying the dynamics of neural activity via electrical recording relies on the ability to detect and sort neural spikes recorded from a number of neurons by the same electrode. This article reviews methods for detecting and classifying action potentials, a problem commonly referred to as spike sorting.

Figure 1. Extracellular recordings and spike sorting. (A) The extracellular activity of neurons is recorded with microwires inserted in the brain. The spikes of neurons close-by the electrode tip (in red and blue) can be separated via spike sorting; neurons further away (in dark grey) can be detected but not sorted, thus generating the multiunit activity; more distant neurons (in light gray) co...
متن کاملA 130-μW, 64-Channel Spike-Sorting DSP Chip
Spike sorting is an important processing step in various neuroscientific and clinical studies. An on-chip spikesorting DSP must provide data-rate reduction while maintaining a power density much less than 800 μW/mm. Most existing designs either provide only spike detection for multi-channel processing, or they provide detection and feature extraction only for a single channel. We demonstrate a ...
