Dynamics of Perceptual Bistability: e.g., the Necker Cube

  When visualizing an ambiguous scene (such as the Necker cube) one may perceive ongoing temporal alternation (time scale, seconds) between the possible interpretations. Various dynamical models lead to alternating mutual exclusivity with neuronal competition implemented as reciprocal inhibition between neuronal populations. Is switching due to adequately strong slow negative feedback or induced by noise operating on a bistable system?
