Abstract

Spike sorting is the process of separating the extracellular recording of the brain signal into one unit
activity. There are a number of proposed algorithms for this purpose, but there is still no acceptable
solution. In this paper a spike sorting method has been proposed based on the Euclidean distance of the
most effective features of spikes represented by principle components (PCs) of the detected and aligned
spikes. The assessments of the method, based on signal-to-noise ratio (SNR) representing background
noise, showed that the method performed spike sorting to a high level of accuracy.
