Abstract

In the experiment reported in this paper, 22 of 35 neurons in the gustatory NTS were found to respond to odorant as well as taste stimuli. This odorant response was apparently mediated by the ethmoid nerve and at least one other odorant-responsive system, possibly other nasal trigeminal afferents. These gustatory neurons responded to odorants, as they did to taste stimuli, in a manner consistent with an encoding of stimulus quality information. Thus at least some of the neurons of the gustatory NTS carry information concerning several of the senses involved in ingestion.

摘要

在本文所报道的实验中，发现味觉孤束核中的35个神经元中有22个对气味剂以及味觉刺激均有反应。这种对气味剂的反应显然是由筛神经和至少一种其他的气味剂反应系统介导的，可能还有其他鼻三叉神经传入纤维。这些味觉神经元对气味剂的反应，与它们对味觉刺激的反应一样，其方式与刺激质量信息的编码一致。因此，味觉孤束核中至少有一些神经元携带与摄入过程中涉及的几种感觉有关的信息。
