Chequerboard pattern reversal using a modified television display to measure visual evoked responses.
The clinical value of visual evoked response measurement is noted with particular reference to the stimulus source used. The complexities of response to brief flashes of light has led to the increased use of chequerboard reversal as a stimulus source. Thus far, the chequerboard reversal has been produced by opto-mechanical means. This paper presents the results of using a television display as the stimulus generator, and some of the advantages of such a purely electronic source of pattern reversal are discussed.
