Abstract
In the experience of eating foods or drinking beverages, among other sensations, taste and smell often occur coincidentally. It’s understudied how the higher order cortical regions that process taste and smell interact. It is known that chemosensory cortical areas can respond to multimodal chemosensory stimuli such the gustatory cortex exhibiting both taste and odor stimuli responses but it is unclear whether the interactions and exchange of signals between these two areas influence these responses. Intertwined with this question is whether there is a coherent response occurring simultaneously in both of these regions and to what degree it depends on if smell is delivered retronasally (through the mouth) or orthonasally (into the nares). We demonstrate interactions of this chemosensory cortical network with dual site electrophysiological recordings, advanced imaging, and behavioral analysis.
