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?
