Modeling of visual cortex

We simulate laminar cortical structure of V1 and V2 with neurons that obey shunting equations (first order approximation of Hodgkin-Huxley equations) and constraint the resultant cortical structure with neurophysiological and psychophysical data to reach a better explanation of some basic visual phenomena including figure-ground segregation, boundary ownership, the role of contrast relations in the perception of surfaces in depth, illusory contours and subjective surfaces.
