Our knowledge regarding the neural processing of the three chemical senses has been lagging behind that of our other senses considerably. It is only during the last 25 years that significant advances have been made in our understanding of where in the human brain odors, tastants, and trigeminal stimuli are processed. Here we provide an overview of the current knowledge of how the human brain processes chemical stimuli based on findings in neuroimaging studies using positron emission tomography and functional magnetic resonance imaging. Additionally, we provide new insights from recent meta-analyses, based on all published neuroimaging studies of the chemical senses, of where the chemical senses converge in the brain.
我们对三种化学感觉的神经处理的了解,相比其他感觉,一直相当滞后。直到最近25年,我们才在理解人类大脑中气味、味觉刺激物和三叉神经刺激的处理位置方面取得了重大进展。在此,我们根据正电子发射断层扫描和功能磁共振成像等神经影像学研究的结果,概述目前人类大脑处理化学刺激的相关知识。此外,我们还基于所有已发表的化学感觉神经影像学研究的最新荟萃分析,提供了关于化学感觉在大脑中汇聚位置的新见解。
