The brain contains specific neural circuits for integrating taste and odor information.

“Now we can go to the brain of this mice and go to this area that we now uncover, discover as being the side of multisensory integration between taste and odor, and silence it, prevent it from being activated experimentally. And if that area really represented the integration of these two, the animals should still be able to recognize the taste alone. They still should be able to recognize the other alone, but should be incapable now to recognize the mix, and exactly as predicted.”
