The multisensory nature of unisensory cortices: a puzzle continued.

Multisensory integration is central to perception, and recent work drafts it as a distributed process involving many and even primary sensory cortices. Studies in behaving animals performing a multisensory task provide an ideal means to elucidate the underlying neural basis, and a new study by Lemus et al. in this issue of Neuron thrusts in this direction.
