Abstract

A laminar model of the layer 4 of area V1 of mammals is presented. The model addresses development as well as functional roles of the horizontal connections found in this cortical layer. It is assumed that the layer 4 is subject to visual experience at the eye opening. It is further assumed that the LGN input is poorly tuned for orientations. These two assumptions are sufficient for modeling how a correlation based network of horizontal connections is developed in layer 4. These assumptions are in line with reports on rapid improvement of OS during the first weeks after eye opening, when the eyes are subject to normal visual experience. This period in an animal’s life coincides with the development of the cortical horizontal connections as well.
