info-theoretic spike-triggered average and covariance (iSTAC) estimator
description: MATLAB code - estimates a set of linear filters (or "receptive fields") using an information-theoretic objective that optimally combines information from spike-triggered average and spike-triggered covariance. The filters can be considered as the first stage in a linear-nonlinear-Poisson (LNP) model of the neuron's response. They are sorted by informativeness, providing an estimate of the single-spike information captured by each additional filter.
