What is Properties of Visual Evoked Potentials to Onset of Movement on a Television Screen about?

In 80 subjects the dependence of movement-onset visual evoked potentials on some measures of stimulation was examined, and these responses were compared with patternreversal visual evoked potentials to verify the effectiveness of pattern movement application for visual evoked potential acquisition. Horizontally moving vertical gratings were generated on a television screen. The typical movement-onset reactions were characterized by one marked negative peak only, with a peak time between 140 and 200ms. In all subjects the sufficient stimulus duration for acquisition of movement-onset-related visual evoked potentials was lOOms; in some cases it was only 20ms. Higher velocity (5.6 ~ produced higher amplitudes of movement-onset visual evoked potentials than did the lower velocity (2.8 ~ In 80% of subjects, the more distinct reactions were found in the leads from lateral occipital areas (in 60% from the right hemisphere), with no correlation to handedness of subjects. Unlike pattern-reversal visual evoked potentials, the movement-onset responses tended to be larger to extramacular stimulation (annular target of 5 ~ ~ than to macular stimulation (circular target of 5 ~ diameter).
