Modeling perceptual multi-stability with Hodgkin-Huxley neurons

Perceptual multi-stability can be induced by either using some ambiguous figures (such as Neckar Cube or Face/ Vase figure) or showing different images to left and right eyes (binocular rivalry). The observer experience a persistent switching between different perceptual representations of the same image. The switching process is spontaneous and irregular: time intervals between consequent switching would form some Gaussian-like distribution [1,2]. Switching is highly involuntary and usually human subjects cannot use their will power to control the process. Many behavioral experiments have been carried out. Levelt [3,4] found that during binocular rivalry, when the image brightness to one eye increased, the mean duration of perception from the other eye decreased (but little was change on the duration from the same eye). Leopold et al. [5] found that for ambiguous figures, the switching process would slow down if the figure appeared and disappeared periodically.
