[The relationship of amplitude of visual evoked potentials to side length of rectangular stimulus pattern and to abruptness of stimulus alternation (author's transl)].
Cortical potentials evoked by viewing checkerboard pattern reversal stimuli as well as horizontal and vertical rectangular pattern reversal stimuli were recorded. The amplitude of the cortical evoked responses decreased with increasing side length of the rectangular pattern and decreasing velocity of the pattern reversal. Psychophysical and electrophysiologic findings are compared with these data and their clinical relevance is discussed.
