Neurobiologists have traditionally assumed that multisensory integration is a higher order process that occurs after sensory signals have undergone extensive processing through a hierarchy of unisensory subcortical and cortical regions. Recent findings, however, question this assumption. Studies in humans, nonhuman primates and other species demonstrate multisensory convergence in low level cortical structures that were generally believed to be unisensory in function. In addition to enriching current models of multisensory processing and perceptual functions, these new findings require a revision in our thinking about unisensory processing in low level cortical areas.
传统上，神经生物学家认为多感官整合是一个高阶过程，它发生在感觉信号经过单感官的皮层下和皮层区域层次结构的广泛处理之后。然而，最近的研究结果对这一假设提出了质疑。对人类、非人类灵长类动物和其他物种的研究表明，在通常被认为具有单一感觉功能的低级皮层结构中存在多感官融合。除了丰富当前的多感官处理和感知功能模型外，这些新发现还需要我们重新思考低级皮层区域的单感官处理。
