1. A method for determining the specific anatomical localization of dysfunction in temporal lobe epilepsy comprising the steps of: placing a plurality of electrodes with respect to physical areas of the subject's brain; generating a pseudorandom, repeatable, broadband visual stimulus; summing the broadband visual stimulus on the retina and associated neural networks of the subject; amplifying the electrical analog response signal measured by each of the placed electrodes; recording the amplified analog response signal from each electrode; resynthesizing the broadband visual stimulus; cross-correlating the resynthesized broadband visual stimulus with the recorded analog response signal for each placed electrode to obtain at least a first, second and third order Wiener kernel representation thereof; limiting the bandwidth of the visual stimulus by masking out those portions which produce non-significant electrical analog responses; summing the bandwidth-limited visual stimulus on the retina and associated networks of the subject; amplifying the bandwidth-limited electrical analog response signal measured by each of the placed electrodes; recording the amplified bandwidth-limited electrical analog response signals from each electrode; resynthesizing the bandwidth-limited visual stimulus; cross-correlating the resynthesized bandwidth-limited visual stimulus with the stored bandwidth-limited analog response signal for each electrode to recompute at least a first, second and third order Wiener kernel representation thereof; synthesizing an optimal kernel-defined visual stimulus .LAMBDA. for each of said electrodes by multiplying the resynthesized bandwidth-limited visual stimulus by the recomputed Wiener kernel representation of the system; presenting an optimal .LAMBDA.-defined visual stimulus to the subject for each placed electrode; summing the .LAMBDA.-defined visual stimulus on the retina and associated neural network of the subject; determining which of the .LAMBDA.-defined visual stimuli produced neurophysiologically significant responses in the subject; and utilizing the known locations of those placed electrodes whose .LAMBDA.-defined visual stimuli produced said significant responses and the nature thereof to specifically isolate the anatomical location of the dysfunction.
