Spike sorting with gaussian mixture models
WebOct 1, 2015 · Basic steps for spike sorting. Starting from the recorded raw data, (i) a bandpass filter is applied, e.g., between 300 Hz and 3000 Hz, to keep the most useful part of the spectrum for spike sorting. Next, (ii) spikes are detected, usually using an amplitude threshold applied to the filtered data. WebThis study investigates how these differences impact on a real study of spike sorting, for the estimation of multivariate Gaussian location-scale …
