Some evidence is available to show that psychological stimulation has certain effects on the physiology of the human brain. For instance, hemisphere-specific stimulation through the presentation of words flashed in a visual hemifield appears to modify the electrophysiological activity of the contralateral hemisphere in dyslexic children and to affect their subsequent reading performance.
