Computer Simulation of Interactions Responsible for Length and Width Tuning in the Striate Cortex
Overview This paper describes a simulation of the long-range inhibitory interactions that produce end-stopping, surround-stopping and side-stopping in the primary visual cortex. Unlike previous models, but in line with recent understanding, the approach used here incorporates a divisive rather than a subtractive influence from the receptive field surround, and includes phase independent inhibition from a neural pool with broad orientation and spatial frequency selectivity. This approach is successful at producing realistic tuning for stimulus length and curvature without the problems of false responses or critical dependencies on stimulus position that other researchers have experienced.
