Abstract
A neural network model with incremental Hebbian learning of afferent and lateral synaptic couplings is proposed, which simulates the activity-dependent self-organization of grating cells in upper layers of striate cortex. These cells respond vigorously and exclusively to bar gratings of a preferred orientation and periodicity. Response behavior to varying contrast and to an increasing number of bars in the grating shows threshold and saturation effects. Their location with respect to the underlying orientation map and their formation relative to each other. The number of emerging grating cells is controlled by the range and strength of the lateral coupling structure.
