Computer simulation was used in a study of the dynamical behaviour of an anatomically-realistic model of the primary visual cortex. The model incorporated the inter-layer connections in a given cortical area, and also the forward and reverse projections by which adjacent areas in the visual hierarchy interact. It was found that the dynamical behaviour of a two-area model displayed oscillations at a frequency of around 50Hz, which lies in the so-called gamma band. The observed oscillations may have the same origin as those recently seen experimentally under certain conditions in the visual systems of cats.
