Spike Sorting by Joint Probabilistic Modeling of Neural Spike Trains and Waveforms

Table 1

Breakdown of parameter set 𝜆=[𝜃,𝜙_init,𝜙_isi] and probability distributions for joint waveform and firing rate spike sorting.

Waveform	Gaussian	𝜃𝑗={𝝁𝑗,𝚺𝑗}
First firing [𝑤𝑗]	Poisson	𝜙init,𝑗={𝛽𝑗}
ISI [𝑓𝑗]	Log-normal	𝜙isi,𝑗={𝜇𝑗,𝜎^2𝑗}
