Analysis of X- and Y-Like Visual Function in Man Using the Cortical Evoked Potential.

Abstract

A facility has been created which can objectively assess a human observer's acuity, contrast sensitivity, and neural transmission time between eye and brain, all by directly recording the brain's response with simple scalp electrodes. A start has been made in using these capabilities to separate responses originating in two subdivisions of the visual system, namely the division specialized for pattern and for movement perception. The techniques now have potential both for detecting disease and as a research tool for understanding visual function.
