Coding of luminance and color differences on neurons in the rabbit's visual system.

The neuronal activity in the rabbit's visual cortex, lateral geniculate nucleus and superior colliculus was investigated in responses to 8 color stimuli changes in pairs. This activity consisted of phasic responses (50-90 and 130-300 Ms after stimuli changes) and tonic response (after 300 Ms). The phasic responses used as a basis for the matrices (8 x 8) constructed for each neuron included the average of spikes/sec in responses to all stimuli changes.
