Abstract
ALTHOUGH there have been many reports about human averaged evoked potentials to visual stimulation, the relation of these scalp-recorded potentials to their underlying sources is obscure, although stimulus-related visual evoked potential (VEP) components are generally thought to originate in the visual cortex. Most cells in the visual cortex of animals such as the cat and monkey are contour-sensitive1–3, and so studies involving patterned or contoured stimulation seem most likely to provide such information. I report here some preliminary results which illustrate the great influence of the location of a retinal stimulus on the characteristics of pattern-related VEPs, and indicate how such studies provide clues to the probable location of the sources of different components of these VEPs.
