Abstract : The present study is designed to measure the response of relatively isolated photoreceptor units under experimental conditions comparable to those found in psychophysical investigations of human early dark adaptation. The term 'relatively isolated photoreceptor unit' is used to indicate cognizance of the fact that lateral interaction effects may influence the response under appropriate conditions of stimulation. The principal objective of the investigation is to determine whether the outstanding features of the psychophysical data can be reproduced or approximated electrophysiologically.
