Figure 7: (a) represents two disparity cells that are allowed to develop under individual bias but no neighborhood influence. They usually develop to have different disparity tuning. (b) When the same disparity cells are connected by means of a diffusive resistor (100 ohms), the more strongly biased cell influences the development of the other cell and they form cluster of the same feature preference. On a larger scale this leads to the formation of feature maps.
