抄録

Sensory perception has been traditionally investigated one modality at a time, but real world perception and behavior are driven by the integration of information from multiple sensory sources. In traditional models of the sensory brain, multisensory integration is deferred until after extensive unisensory processing has occurred. Rapidly accumulating evidence on multisensory processing in mammals challenges this classical view. Anatomical studies suggest that the substrate for multisensory integration is already present at the primary sensory cortices. Furthermore, it has been shown that the activity of auditory thalamus is strongly influenced by visual stimuli, when presented in conjunction with auditory stimuli. These findings strongly indicate that the neural underpinnings of multisensory integration extend into the very early stages of sensory processing.
