Averaged evoked potentials (AEP) to verbal (letters) and nonverbal (random shapes) stimuli exposed in the left and right visual fields were registered in healthy subjects with normal vision. Analysis of the later AEP latencies pointed to asymmetry in the temporal parameters of the interhemispheric interaction. The late AEP latency is shorter in the right hemisphere than in the left hemisphere. The difference is more pronounced in responses to nonverbal stimuli. The earlier development of the evoked potential in the right hemisphere (or the later one in the left hemisphere) accounts for the interhemispheric difference in the temporal parameters of the late AEP components. Comparison of the latency of the component P300 to verbal and nonverbal stimuli presented in the ipsilateral or the contralateral visual fields reveals a transfer of the results of the cortical processing of visual information in the course of interhemispheric interaction.
在视力正常的健康受试者中记录了对呈现于左、右视野的言语（字母）和非言语（随机形状）刺激的平均诱发电位（AEP）。对后期AEP潜伏期的分析表明，半球间相互作用的时间参数存在不对称性。右半球的后期AEP潜伏期比左半球短。这种差异在对非言语刺激的反应中更为明显。右半球诱发电位的较早发育（或左半球的较晚发育）解释了后期AEP成分时间参数的半球间差异。对同侧或对侧视野中呈现的言语和非言语刺激的P300成分潜伏期进行比较，揭示了在半球间相互作用过程中视觉信息皮质处理结果的转移。
