[Visual evoked potentials and the time of motor reaction to visual stimuli in chronic metallic mercury poisoning]

In a group of 10 patients with diagnosed occupational chronic poisoning with metallic mercury a correlation was sought between the parameters of the visual evoked potentials and the results of the psychological test evaluating the rapidity of motor response to the visual stimuli. The analysis suggest a cerebral dysfunction of the visual neurons and reduced rate of visual information transformation to the motor effector at the level of the cortical association centre.
