在本研究中，我们操纵了听觉和视觉输入之间的时间异步性，并将多感觉刺激诱发的事件相关电位与相同时间异步性的单感觉-听觉(A)和单感觉-视觉(V)刺激诱发的事件相关电位的总和进行了对比。我们的目标是研究时间不同步对多感觉整合的影响。在我们的实验中，多感觉刺激中的听觉和视觉输入具有-300ms、0ms或300ms的刺激异步性(SOA)。结果表明，当听觉和视觉输入同步时，多感觉整合发生在听后110~160ms、210~250ms和300~350ms的时间窗内。当听觉发作先于临界动作发作300ms时，多感觉整合发生在听觉发作后110~160ms和300~350ms的时间窗内。当临界动作开始时间比听觉开始时间早300ms时，多感觉整合发生在听觉开始后110~160ms、210~250ms、290~320ms和350~400ms的时间窗内。此外，在110-160ms和210-250ms的时间窗内，听觉和视觉输入同步时的整合较强，而在250-400ms的时间窗内，多感觉整合会因SOA的不同而不同。结果表明，无论听觉输入和视觉输入之间的异步性如何，多感觉整合都会发生，并且多感觉整合会受到时间异步性的影响。(C)2011年IBRO。爱思唯尔有限公司出版。保留所有权利。
In this study, we manipulated the temporal asynchrony between auditory and visual inputs, and contrasted event-related potentials (ERPs) evoked by multisensory stimuli with the summation of the ERPs evoked by unisensory-auditory (A) and unisensory-visual (V) stimuli with the same temporal asynchrony. Our goal was to investigate the influence of temporal asynchrony on multisensory integration. In our experiment, the auditory and visual inputs in the multisensory stimuli had a stimulus onset asynchrony (SOA) of -300 ms, 0 ms, or 300 ms. The results suggested that when the auditory and visual inputs were synchronous, multisensory integrations would occur in the time windows of 110-160 ms, 210-250 ms and 300-350 ms after auditory onset. When the auditory onset preceded the critical action onset by 300 ms, multisensory integrations were involved in the time windows of 110-160 ms and 300-350 ms after auditory onset. When the critical action onset preceded the auditory onset by 300 ms, multisensory integrations would occur in the time windows of 110-160 ms, 210-250 ms, 290-320 ms and 350-400 ms after auditory onset. In addition, in the time windows of 110-160 ms and 210-250 ms, the integrations were stronger when the auditory and visual inputs were synchronous, and in the time window of 250-400 ms, multisensory integrations would be different as the SOAs were different. It was suggested that multisensory integration would occur regardless of the asynchrony between auditory and visual inputs, and multisensory integration could be influenced by temporal asynchrony.
