摘要

大多数功能性磁共振成像(fMRI)对味觉的研究提供了大约45?Min反复取样大脑对味觉的反应。在这段时间内，参与者经常报告他们的小便需求增加。由于味觉和内感受信息都在岛叶前部皮层中表现，我们在两个数据集(n?=?45)中评估了感知到的排尿需求是否会影响接收少量奶昔时的岛叶反应。扫描前后排尿欲望评分的变化与前岛叶对奶昔的反应呈负相关。这一发现表明排尿驱动影响了岛叶对奶昔的反应，并支持了先前关于人类前岛叶皮层中味觉和内脏表征重叠的报道。

Micturition Drive is Associated with Decreased Brain Response to Palatable Milkshake in the Human Anterior Insular Cortex

Most functional magnetic resonance imaging (fMRI) studies of taste deliver small quantities of liquids over roughly 45?min to repeatedly sample brain response to tastants. Within this time participants frequently report that their need to urinate increases.

Since both gustatory and interoceptive information are represented in the anterior insular cortex, we evaluated whether perceived need to urinate influenced insular responses to the receipt of a small bolus of milkshake in two datasets (n?=?45).

Change in pre- to post-scan ratings of desire to urinate was inversely related to anterior insular response to milkshake.

This finding demonstrates that micturition drive influences insular response to milkshake and supports previous reports of overlapping gustatory and visceral representation within human anterior insular cortex.
