A 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 کاملSpike Train Decoding Without Spike Sorting
We propose a novel paradigm for spike train decoding, which avoids entirely spike sorting based on waveform measurements. This paradigm directly uses the spike train collected at recording electrodes from thresholding the bandpassed voltage signal. Our approach is a paradigm, not an algorithm, since it can be used with any of the current decoding algorithms, such as population vector or likelih...

متن کاملCompressed Sampling for Spike Sorting
Our goal is to demonstrate the usefulness and efficiency of a compressed sensing approach when applied to the problem of spike sorting. This approach involves four steps towards transforming the raw spikes into a sparse basis with the fewest number of measurements require to achieve accurate clustering. We first train a dictionary which converts a spike into a sparse signal. We then sample the ...
