Abstract

Binocular rivalry is the alternation of perception that occurs whenstimuli to the two eyes are sufficiently different that they cannot becombined into a single visual percept. Binocular rivalry wasmathematically modeled using a reciprocal inhibition oscillatornetwork that is based on the gated pacemaker model of Carpenter &Grossberg (1983). The model uses multiple gating of recurrent signalsby slowly habituating chemical transmitters at nonlinearinterneurons. These slowly habituation gates drive switches betweencompeting populations. The model was evaluated by computersimulation. The results show that the model performs well withrespect to psychophysical data including all of Levelt's (1965)propositions, the constant depth-of-suppression criteria of Fox & Check(1972), and under the binocular rivalry stimulus paradigm employed byMeuller & Blake (1989). It is concluded that this is biologicallyplausible neural network can accurately predict the temporal dynamicsof binocular rivalry.Note: see original abstract for references.
