Direct piriform-to-auditory cortical projections shape auditory-olfactory integration.

All living organisms exist within multisensory environments, yet there is a lack in our understanding of how the brain integrates multisensory information. This work elucidates novel circuits governing auditory-olfactory integration in the auditory cortex. Our results shed new light on a relatively understudied area of multisensory research, promising a more robust understanding of how animals and humans perceive and interact within complex environments.
