[The effect of amplitude-frequency characteristics of the noise-covered test stimulus on the form of visual evoked potentials].
Visual evoked potentials in response to reverse checkerboard patterns presented in additive noise were analyzed. An induced by noise changes in visual evoked potentials form and in amplitude-frequency spectrum of checkerboard patterns were compared. It was found that character of visual evoked potentials form alteration correlated with stimulus amplitude-frequency spectrum alterations. Results obtained here support Gestalt-psychology view about using by visual system a spatial-frequency but not a discrete information description.
