  • Matlab tutorial code for Spike-triggered Covariance: STCtutorial.tar.gz
    Based on Spike-triggered Neural Characterization. O Schwartz, J W Pillow, N C Rust, and E P Simoncelli. Journal of Vision, 2006. The code includes example simulations for model neurons and Gaussian inputs, with a choice of several model neurons (simple cell, complex cell, divisive normalization), and then code for the Spike Triggered Average and Covariance, and plotting of the eigenvalues and eigenvectors (estimated filters), and some simple plots of the nonlinearities. The best way to go through it is line by line, copying each time portions from the m file into Matlab.
