Taste remains one of the least-explored human senses. Cortical taste responses were investigated using neuroimaging in 40 subjects tasting a range of different taste stimuli compared to a neutral tasteless control. Activation was found in the anterior insula/frontal opercular taste cortex and caudal orbitofrontal cortex, both areas established as taste cortical areas by neuronal recordings in primates. A novel finding in this study was a highly significant response to taste in the dorsolateral prefrontal cortex. This may reflect an effect of taste on cognitive processing to help optimise or modify behavioural strategies involved in executive control; or it could reflect the engagement of this region in attentional processing by a taste input.
味觉仍然是人类探索最少的感官之一。我们对40名受试者进行了神经成像研究，观察他们在品尝一系列不同味觉刺激时的皮质味觉反应，并与无味觉的中性对照进行比较。在前脑岛/额下回味觉皮质和尾侧眶额皮质发现了激活，这两个区域在灵长类动物的神经元记录中均被确定为味觉皮质区域。本研究的一个新发现是背外侧前额叶皮质对味觉有高度显著的反应。这可能反映了味觉对认知加工的影响，以帮助优化或修改执行控制中涉及的行为策略；或者它可能反映了该区域通过味觉输入参与注意力加工。
