Sensory cortices encode information from more than one sensory modality
A classical view of multisensory perception deferred the merging and representation of multisensory information to higher association areas, and posited that a large part of the sensory processing can be reduced into a collection of independent unisensory systems. Recent neuroimaging studies challenged this view and have been successful in showing that primary sensory areas activity can be modulated by sensory input coming from multiple modalities. However, if these multisensory activations are merely sensory unspecific (e.g. attentional) modulations or they actually represent information that corresponds to other sensory modalities is still an open question. In this talk, by using psychophysical and fMRI decoding technics, I will provide converging evidence of the functional involvement of primary sensory areas in the representation of multisensory information.
