The research program aims at incorporating EEG evoked responses in man-machine communication. Present work is toward developing a methodology for the real-time computer discrimination of evoked responses in the EEG. Current experiments are visual evoked responses using colored and patterned visual stimuli. From the ensemble of these experiments, tentative candidate EEG codes have emerged that appear to reflect three retinal processes red-green-blue. These are remarkable results since, while there is good evidence for a trichromatic absorbing structure in the fovea, there was no indication that these processes would be reflected into scalp potentials. Topological Dimensionality studies showed that red and green components, although close in timing, did behave in a clearly distinct manner. The response of the dark adapted eye, a limit case in background levels, was found clearly detached from the cluster in all cases.
