Abstract

The amplitude and latency of visual evoked potentials to pattern-reversal half-field stimulation were measured in 20 normal right-handed subjects to determine whether the individual contribution of right and left cerebral hemispheres is different as related to the generation of pattern-evoked potentials. The amplitude and latency of P1 from a lateral occipital electrode ipsilateral to the halffield stimulation were significantly greater with right half-field wtimulation. The amplitude and latency difference between both sides probably reflects asymmetries of human striate cortex.
