Information from multiple sensory modalities interacts. Using functional magnetic resonance imaging (fMRI), we aimed to identify the neural structures correlated with how cooccurring sound modulates the visual motor response execution. The reaction time (RT) to audiovisual stimuli was significantly faster than the RT to visual stimuli. Signal detection analyses showed no significant difference in the perceptual sensitivity (d') between audiovisual and visual stimuli, while the response criteria (β or c) of the audiovisual stimuli was decreased compared to the visual stimuli. The functional connectivity between the left inferior parietal lobule (IPL) and bilateral superior temporal gyrus (STG) was enhanced in Go processing compared with No-go processing of audiovisual stimuli. Furthermore, the left precentral gyrus (PreCG) showed enhanced functional connectivity with the bilateral STG and other areas of the ventral stream in Go processing compared with No-go processing of audiovisual stimuli. These results revealed that the neuronal network correlated with modulations of the motor response execution after the presentation of both visual stimuli along with cooccurring sound in a multisensory Go/Nogo task, including the left IPL, left PreCG, bilateral STG and some areas of the ventral stream. The role of the interaction between the IPL and STG in transforming audiovisual information into motor behavior is discussed. The current study provides a new perspective for exploring potential brain mechanisms underlying how humans execute appropriate behaviors on the basis of multisensory information.
多模态信息相互作用。使用功能磁共振成像 (fMRI)，我们旨在确定与声音同时出现如何调节视觉运动反应执行相关的神经结构。视听刺激的反应时间 (RT) 明显快于视觉刺激的 RT。信号检测分析表明，视听刺激与视觉刺激之间的感知灵敏度 (d') 没有显著差异，而视听刺激的反应标准 (β 或 c) 则低于视觉刺激。与视觉刺激的 Go 处理相比，视听刺激的 No-go 处理中左顶下小叶 (IPL) 和双侧颞上回 (STG) 之间的功能连接增强。此外，与视听刺激的 No-go 处理相比，Go 处理中左中央前回 (PreCG) 与双侧 STG 和腹侧流的其他区域显示出增强的功能连接。这些结果表明，在多感觉 Go/Nogo 任务中，当同时呈现视觉刺激和同时出现的声音时，与运动反应执行的调制相关的神经元网络包括左 IPL、左 PreCG、双侧 STG 和腹侧流的一些区域。讨论了 IPL 和 STG 之间的相互作用在将视听信息转换为运动行为中的作用。本研究为探索人类如何根据多感觉信息执行适当行为的潜在大脑机制提供了新的视角。
