By extension, we do not consider multisensory integration to be a model, but rather an empirical probe that provides a unique window into the integrative brain and its adaptive nature.Multisensory paradigms provide inputs onto the integrative machinery in the brain that can be segregated to different receptor surfaces and initial input pathways, which facilitates a clean identification of their initial point of convergence; something that is more difficult to do within any of the main sensory modalities.
