Visual evoked potential pattern generation, recording, and data analysis with a single microcomputer.
A single microcomputer is used to generate multiple sets of checkerboard patterns, simultaneously record EEG data for visual evoked potentials, and analyze the results by fast Fourier transform in very rapid sequence under operator control. This system permits efficient estimates of visual acuity in infants with ophthalmological and neuro-ophthalmological disease.
