We have previously developed improved methods to study the cortical representation of taste and retro-nasal aroma stimuli. This study on 6 subjects aimed to assess the cortical representation of taste and retro-nasal aroma associations using fMRI and an improved paradigm. We delivered randomly taste, aroma, taste plus aroma, and control stimuli. We have been able to detect the cortical representation of associations of taste and aroma (versus unimodal taste or unimodal aroma) in a protocol that is closer to the typical experience of consuming liquid foods.
