The amplitudes of transient and steady-state visual evoked potentials (VEPs) were measured during hemifield stimulation of the left eye in 10 healthy adults. Pattern reversal of a checkerboard was produced at 4 stimulation frequencies: 1, 5, 10 and 15 Hz. The amplitudes of pattern VEPs were evaluated using the paired t test to determine significant differences between right and left hemifields. The transient VEP amplitudes from midoccipital, midparietal, ipsilateral occipital and contralateral occipital electrodes were significantly greater with right hemifield stimulation. The steady-state VEP amplitudes from the midoccipital electrode during 15 Hz stimulation were significantly greater with right hemifield stimulation. Our neurophysiological data may be compatible with neuroanatomical asymmetries of the occipital lobes in humans.
在10名健康成年人的左眼半视野刺激过程中，测量了瞬态和稳态视觉诱发电位（VEP）的振幅。在4种刺激频率下产生棋盘格图案反转：1、5、10和15Hz。使用配对t检验评估图形VEP的振幅，以确定左右半视野之间的显著差异。右半视野刺激时，来自枕叶中部、顶叶中部、同侧枕叶和对侧枕叶电极的瞬态VEP振幅显著更大。15Hz刺激期间，来自枕叶中部电极的稳态VEP振幅在右半视野刺激时显著更大。我们的神经生理学数据可能与人类枕叶的神经解剖学不对称性相符。
