THE USE of electroencephalographic recording from newborn infants is gradually becoming an important and effective method of studying the maturation of the brain, especially in relation to stress and the development of later dysfunction.1-6 Responses of the electroencephalogram to sensory stimulation or evoked sensory potentials are being increasingly investigated as a means of evaluating reactivity in involved pathways.7-13 In detailed reports, Ellingson9-11 has described the evoked cortical electroencephalographic responses to visual stimulation in the human infant, focusing mostly on their form, latency, and developmental changes. Although indicating the existence of responses to repetitive stimulation, he found photic "driving" "relatively rarely," in only 5% of infants during the neonatal period; this phenomenon, however, was elicited in 39% of infants 2 weeks of age or over. All investigators have emphasized that the topographical distribution of these responses is limited to the occipital region in the newborn.
