Colloquially referred to as "taste", flavor is in reality a thoroughly multisensory experience. Yet, a mechanistic understanding of the multisensory computations underlying flavor perception and food choice is lacking. Here, we used a multisensory flavor choice task in rats to test specific predictions of the statistically-optimal integration framework, which has previously yielded much insight into cue integration in other multisensory systems. Our results confirm three key predictions of this framework in the unique context of flavor choice behavior, providing novel mechanistic insight into multisensory flavor processing.

口味选择过程中味道和气味线索的自适应加权

通俗地称为“味道”，味道实际上是一种彻底的多感官体验。然而，缺乏对风味感知和食物选择背后的多感官计算的机械理解。在这里，我们在大鼠中使用了多感官风味选择任务来测试统计优化整合框架的特定预测，该框架之前已经对其他多感官系统中的线索整合产生了很多见解。我们的结果证实了该框架在风味选择行为的独特背景下的三个关键预测，为多感官风味处理提供了新颖的机械洞察力。
