Visually evoked potentials and simple reaction times to visual stimuli in chronic disulphide intoxication

The relationship between parameters of visually evoked potentials (VEPs) and the results of a psychological test assessing the speed of motor reaction to visual stimuli was examined in 21 patients with chronic carbon disulphide intoxication. Correlations obtained suggest cerebral disfunction of the visual pathway and diminished ability to transform visual information to motor reaction at the level of the cortical association centre.
