早期的经验决定了感官之间的相互作用。神经生理学杂志97：921-926,2007。2006年8月16日首次出版；DOI：10.1152/jn。00497.2006。多感觉整合是指大脑合成来自不同感官的信息以增强对外部事件的敏感度的过程。在目前的实验中，动物被饲养在一个改变的感觉环境中，在这个环境中，视觉和听觉刺激在时间上耦合，但来自不同的位置。上丘的神经元发展了一种看似异常的多感觉整合形式，其中空间上不同的视觉-听觉刺激被整合的方式与正常饲养动物的神经元整合同一位置的视觉-听觉刺激的方式相同。这些数据表明，管理多感官整合的原则是高度可塑性的，来自不同感官的刺激之间没有整合所需的先验空间关系。相反，这些原则似乎是在生命早期根据动物所处环境的特定特征建立起来的，以便在以后的生活中最好地适应这种环境。
Early experience determines how the senses will interact. J Neurophysiol 97: 921 - 926, 2007. First published August 16, 2006; doi:10.1152/jn. 00497.2006. Multisensory integration refers to the process by which the brain synthesizes information from different senses to enhance sensitivity to external events. In the present experiments, animals were reared in an altered sensory environment in which visual and auditory stimuli were temporally coupled but originated from different locations. Neurons in the superior colliculus developed a seemingly anomalous form of multisensory integration in which spatially disparate visual-auditory stimuli were integrated in the same way that neurons in normally reared animals integrated visual-auditory stimuli from the same location. The data suggest that the principles governing multisensory integration are highly plastic and that there is no a priori spatial relationship between stimuli from different senses that is required for their integration. Rather, these principles appear to be established early in life based on the specific features of an animal's environment to best adapt it to deal with that environment later in life.
