Summary
A simple neural network is used to decode spatial pattern information in measured temporal firing patterns of a cell in the primary visual cortex of a macaque monkey. In this way one can quantify how much information beyond that contained in the average spike count is coded in the temporal modulation of the cell’s activity. Most of the results obtained here are for simple discriminations between spike trains generated by two Walsh-pattern stimuli; some are for a task of identifying the correct one out of 4 such stimuli. A simple information-theoretic analysis of the trained networks indicates that significant extra information, of the order of 50% of that contained in the spike count, is carried in the temporal modulation.
