Processing of visual information was studied on the level of the receptive fields of cat's outer geniculate neurons. The spike activity of single neurons was obtained as a response to geometrically regular bright-dark stripes which enabled further reconstruction of a spatial-time weight function of the neuron's receptive field. This function was obtained as a result of solution of so called "ill posed" problems and quantitatively confirmed the existing physiological supposition that visual receptive fields are dynamically reconstructed in time when received visual stimulation.
