Latency Modulation of Border Ownership Selective Cells in V1-V2 Feed-Forward Model
Border Ownership (BO) selective cells show complex behavior in latency, such as a shorter latency for a farther figural element. The complex behavior of latency would give crucial constraints for understanding the neuronal mechanisms underlying BO selectivity. We propose that the delays in the feed-forward mechanisms of surround modulation account for the characteristics of the latency. Specifically, combinations of delays between V1 cells, surround center and BO-selective cells underlie the latency characteristics. To examine the hypothesis, we constructed the V1-V2 feed-forward model and carried out Monte Carlo simulations with a variety of surround regions. The results indicate that physiologically realistic surround regions reproduce the puzzled behavior of latency. The results support the feed-forward mechanism of surround modulation for the neural mechanism underlying the BO selectivity.
