我們不透過舌頭也可以嘗到味道?

就一般的認知而言，我們要透過舌頭上的味蕾才能長出東西的味道。但是，有生物學家發現，大腦中有特定的區域掌控味覺，他們在一個實驗中，將光纖管與老鼠的腦部連結，透過光纖管發送訊號來刺激老鼠腦內掌管"苦澀"味覺的區域，並發現老鼠皺縮成一團，類似於嘗到苦澀味道的反應。但是實驗中的老鼠沒有實際嘗到苦澀的食物。

科學家在另一個實驗裡讓老鼠品嘗苦澀的食物，同時刺激老鼠大腦掌管"甜味"的區域，讓老鼠覺得食物比較可口。同樣的，老鼠品嘗的食物沒有任何甜味，"甜"的感覺是直接由大腦產生的。所以，我們是否也能品嘗到有甜味的咖啡但是咖啡裡卻沒有加糖呢?這個概念以目前來說聽起來有些科幻。但是今日的科幻是有可能在未來成真的!
