A model-based spike sorting algorithm for removing correlation artifacts in multi-neuron recordings. [PDF]
PLoS ONE, 2013 We examine the problem of estimating the spike trains of multiple neurons from voltage traces recorded on one or more extracellular electrodes. Traditional spike-sorting methods rely on thresholding or clustering of recorded signals to identify spikes ...
