| Research Abstract |
We proposed a mathematical model of self-organization of the geniculocortical inputs and long-range horizontal connections in the layer 2/3 of primary visual cortex which relate to the context dependent visual responses. To reveal the possible involvement of the primary visual cortex in the perceptual transition from component motion to pattern motion with the stimulus contrast of plaid illusion, we performed simulation of a neural network composed of the spiking neuron model, whose retina-LGN-visual cortex afferent connections were determined by the self-organization model, and examined neuronal response properties to plaid stimuli. We found that the component-pattern transition is induced by the regulation of neuronal activities by the intracortical interaction.
