Some early uses of evoked brain responses in investigations of human visual function

Abstract

In the context of the technical possibilities of the time, this paper describes early attempts to employ visual-evoked potentials (VEPs) as a tool for investigating human visual function, focussing on the contributions of Henk Spekreijse and his colleagues. The topics covered are as follows: attempts to distinguish between true pattern-specific VEPs and the effects of responses to changes in local luminance; retinal rivalry and interocular sustained suppression; the implications of VEPs elicited by equiluminant chromatic patterns; VEPs specific to real and apparent motion; stereo VEPs; identification of a visual–auditory convergence area in the human brain.
