Abstract

The temporal dynamics of brightness filling-in were studied through neural network simulation experiments conducted under visual masking stimulus conditions. Grossberg and colleagues have specified a filling-in model called the Boundary Contour System / Feature Contour System (BCS/FCS). The BCS generates boundary segmentation, while the FCS fills-in surface feature within these segmentation boundaries. Simulation experiments demonstrate that the model accurately predicts that area-suppression follows a U-shaped function of forward masking (Stoper & Mansfield, 1978) and demonstrate that the psychophysical findings of Paradiso and Nakayama (1991) which they regarded as being against the BCS/FCS model, actually support the model.

Errata

In Equation 2 the depolarization term should be changed from (-e_ij) to (+i_ij), and the hyperpolarization term should be changed from (-i_ij) to (+e_ij). Note that Equation 2 is never actually used in the simulations, as explained at Equation 10. This correction to Equation 2 has been made in the above PDF file.
