最近对人类和猴子的研究表明，声音刺激会影响初级视觉皮层（V1）的视觉反应。这种影响可以在V1产生，通过直接的听觉投射或来自纹外皮质的反馈投射。为了验证这些假设，皮质活动记录使用光学成像在高时空分辨率从豚鼠视觉皮层的多个区域，视觉和/或听觉刺激。根据听觉和视觉刺激联合引起的反应之间的差异，以及单独的视觉和听觉刺激引起的反应之和，评价视觉-听觉相互作用。视觉和听觉刺激的同时呈现导致V1中的显著相互作用，其发生早于其他视觉区域。当听觉刺激先于视觉刺激时，仅在V1中检测到显著的视听交互。这些结果表明，V1是一个皮质起源的视听互动。
Recent studies in humans and monkeys have reported that acoustic stimulation influences visual responses in the primary visual cortex (V1). Such influences can be generated in V1, either by direct auditory projections or by feedback projections from extrastriate cortices. To test these hypotheses, cortical activities were recorded using optical imaging at a high spatiotemporal resolution from multiple areas of the guinea pig visual cortex, to visual and/or acoustic stimulations. Visuo-auditory interactions were evaluated according to differences between responses evoked by combined auditory and visual stimulation, and the sum of responses evoked by separate visual and auditory stimulations. Simultaneous presentation of visual and acoustic stimulations resulted in significant interactions in V1, which occurred earlier than in other visual areas. When acoustic stimulation preceded visual stimulation, significant visuo-auditory interactions were detected only in V1. These results suggest that V1 is a cortical origin of visuo-auditory interaction.
