The hypothesis was tested that interhemispheric transfer time (IHTT), as measured in the latency of bilaterally recorded visual evoked potentials, is directionally asymmetric, i.e. that an IHTT is faster for transmission from right-to-left hemisphere, than from left-to-right. A meta-analysis of 18 experiments within the published literature reporting visual evoked potential IHTTs indicates a significant experiment-wise predominance of faster right-to-left IHTTs. A new experiment is also reported in which significantly faster right-to-left IHTT was found in visual evoked potentials recorded from parietal electrodes to lateral visual field presentations while subjects performed a task requiring complex stimulus recognition and analysis, and a choice response.
通过双侧记录视觉诱发电位的潜伏期测得的半球间传递时间（IHTT）存在方向不对称性，即从右半球到左半球的IHTT比从左半球到右半球的IHTT更快。对已发表文献中报告视觉诱发电位IHTT的18项实验进行的荟萃分析表明，从右到左的IHTT更快在实验层面上具有显著优势。本文还报告了一项新实验，该实验发现，当受试者执行一项需要复杂刺激识别与分析以及选择反应的任务时，从顶叶电极记录到的针对外侧视野呈现的视觉诱发电位中，从右到左的IHTT明显更快。
