Abstract

We construct a dynamical model of the population activity of neurons in the primary visual cortex in response to a moving stimulus. Realistic, time dependent receptive fields were used to model the response of individual neurons. The parameters of the receptive fields were derived from a combination of cortical feature maps and experimentally observed distributions. We compare the predictions of the model with the results of optical imaging experiments and electrophysiological measurements. We also evaluate the abilities of several coding techniques to extract the information about the stimulus parameters and compare them with psychophysically measured performance.
