A Hierarchical Model of Visual Rivalry.

In NIPS 9, 48-54.
Abstract
Binocular rivalry is the alternating percept that can result when
the two eyes see different scenes. Recent psychophysical evidence
supports an account for one component of binocular rivalry similar
to that for other bistable percepts. We test the hypothesis
(Logothetis & Schall, 1989; Leopold & Logothetis, 1996; Logothetis,
Leopold & Sheinberg, 1996) that alternation can be generated by
competition between top-down cortical explanations for the inputs,
rather than by direct competition between the inputs. Recent
neurophysiological evidence shows that some binocular neurons are
modulated with the changing percept; others are not, even if they
are selective between the stimuli presented to the eyes. We extend
our model to a hierarchy to address these effects.
