デンマークのコペンハーゲン大学の研究チームは、食事中に聴く音楽が、脳による味覚の処理に影響を与える仕組みを明らかにした。研究では28人の参加者を対象に、機能的磁気共鳴画像法(fMRI)を用いて脳活動を測定し、音楽を聴く場合、甘味・酸味の溶液を味わう場合、音楽と味覚を同時に体験する場合を比較した。その結果、音楽と味覚を組み合わせると、味覚処理や口腔内の感覚に関わる脳領域の活動が強まることが確認された。これは、味が舌の受容体からの信号だけで決まるのではなく、聴覚など複数の感覚情報を脳が統合することで形成されることを示している。音楽によって甘味や酸味の感じ方を調整する「サウンド・シーズニング」の生物学的根拠を示す成果であり、飲食店や病院、給食施設などで食事体験を改善する可能性がある。特に、食欲低下や低栄養のリスクがある人への応用が期待される。ただし、参加者数は少なく、実際の食品や多様な年齢・文化背景を含めた追加検証が必要である。

The figure shows what happens in the brain when taste is combined with music. On the left (A), sweet taste is paired with music associated with sweetness and compared with sweet taste alone. On the right (B), the same comparison is shown for sour taste. The yellow and orange areas indicate regions where the brain responds more strongly when music and taste are experienced together. These include areas involved in processing taste and sensory signals from the mouth. The findings show that what we hear can influence how the brain processes what we taste. Seeberg et al. (2026)

Abstract

Eating is one of the most fundamental multisensory experiences, yet the neural mechanisms that integrate auditory and gustatory inputs in humans remain underexplored. This study examined how music influences the brain’s encoding of taste. We collected functional magnetic resonance imaging (fMRI) and behavioural data from 28 participants across three conditions: taste only, music only, and music–taste combinations. In the scanner, participants received sweet and sour aqueous solutions, accompanied by musical soundtracks composed to convey sweetness or sourness. In a behavioural session, participants rated each stimulus or combination for pleasantness, intensity, and sound–taste congruency. fMRI results revealed that sweet and sour music and taste stimuli engaged overlapping anatomical regions, particularly within peri-rolandic and medial prefrontal areas. Although voxel-wise conjunction did not identify suprathreshold overlap for sweet stimuli, regional co-localisation was observed in gustatory and reward-related regions, including the rolandic operculum, postcentral gyrus, and gyrus rectus. For sour stimuli, a small but significant voxel-wise conjunction emerged in the right postcentral gyrus. Crucially, concurrent music–taste stimulation elicited stronger activation in gustatory and sensorimotor cortices compared to taste alone, indicating multisensory enhancement. Direct contrasts between congruent and incongruent pairings revealed limited but selective congruency effects: when sweet taste was paired with congruent versus incongruent music, increased activation was observed in bilateral superior temporal gyri and rolandic operculum. Overall, these findings suggest that neural enhancement was primarily driven by the presence of simultaneous multimodal input, with additional modulation under specific congruent pairings. Behaviourally, participants perceived congruent music–taste pairings as more congruent and more pleasant, with modest trends toward increased taste intensity in the presence of music. These findings provide novel insight into the neural basis of sound–taste interactions and contribute to our understanding of how auditory cues can shape flavour perception through multisensory integration.
