Stimulus value gates multisensory integration.

ABSTRACT: The brain enhances its perceptual and behavioral decisions by integrating information from its multiple senses in what are believed to be optimal ways. This phenomenon of "multisensory integration" appears to be pre-conscious, effortless, and highly efficient. The present experiments examined whether experience could modify this seemingly automatic process. Cats were trained in a localization task in which congruent pairs of auditory-visual stimuli are normally integrated to enhance detection and orientation/approach performance. Consistent with the results of previous studies, animals more reliably detected and approached cross-modal pairs than their modality-specific component stimuli, regardless of whether the pairings were novel or familiar. However, when provided evidence that one of
