Moreover, the use of the multiple anatomical substrates of integration is also likely to be context dependent. For example, different potential sources of multisensory influences on low-level sensory cortices have been put forward, including direct ‘‘crossing’’ projections from sensory cortices of different modalities,direct ascending inputs from so-called ‘‘nonspecific’’ thalamic regions,as well as more indirect feedback inputs from higher-order multisensory cortical regions
