Interest and validity of the additive model in electrophysiological studies of multisensory interactions

摘要

Over the past decades, the Stein group has provided a fundamental neural model of multisensory integration at the single-neuron level in animals. They have shown in cat and monkey that when inputs from different modalities are presented in close temporal and spatial proximity, multisensory neurons in the superior colliculus (SC) can increase their firing rate to a level exceeding that predicted by summing the responses to each unimodal cue (review in Stein and Meredith 1993).
