鼻内三叉神经的功能越来越被理解为人类化学感觉感知的一个组成部分。几乎所有的气味都能产生灼热、刺痛、温暖、凉爽或瘙痒等感觉，因此嗅觉缺失者可以感知到这些感觉。对三叉神经刺激的电生理反应允许在包括外周或皮层的不同处理水平上对三叉神经介导的信息进行特定评估。关于这些过程的定位信息可以从脑磁图记录或功能成像数据中获得。当使用这些技术与心理物理措施相结合时，似乎有可能具体描述刺激的处理如何以及在何处发生，它如何与嗅觉介导的感觉相互作用，以及它如何被调节，例如通过环境影响或镇痛药物。(C)2000 Elsevier Science B.V.保留所有权利。
Intranasal trigeminal function is more and more understood as an integral part of human chemosensory perception. Sensations like burning, stinging, warmth, coolness, or itching are produced by almost all odorants so that they can be perceived by anosmics. Electrophysiological responses to trigeminal stimuli allow the specific assessment of trigeminally mediated information at different levels of processing including the periphery or the cortex. Information regarding the localization of these processes can be derived from magnetoencephalographic recordings or functional imaging data. When using these techniques in combination with psychophysical measures, it seems to be possible to specifically describe how and where the processing of irritation takes place, how it may interact with olfactory mediated sensations, and how it is modulated, e.g. by environmental influences or analgesic drugs.
