Receptive fields (RFs) in the oral cavity were examined for 24 taste and 20 mechanoreceptive neurons in the parabrachial nucleus (PB) of anesthetized rats. All of the units studied had an RF on the ipsilateral half of the oral cavity. About half of the units in each category had at least two separate RFs. Most of the 'taste neurons', i.e. units receiving taste inputs, were activated by mechanical stimulation and some of them had a complex RF, e.g. separated into two parts, one on the tongue for taste and one on the palate for mechanical stimulation. The present findings show that the afferent inputs of two modalities from the tongue and palate converge on the PB neurons.
在麻醉大鼠的臂旁核（PB）中，对24个味觉神经元和20个机械感受神经元的口腔感受野（RFs）进行了检查。所有研究的神经元在同侧口腔半部均有一个感受野。每一类中的大约一半神经元至少有两个独立的感受野。大多数“味觉神经元”，即接受味觉输入的神经元，会被机械刺激激活，其中一些具有复杂的感受野，例如分为两部分，一部分在舌上用于味觉，一部分在上腭用于机械刺激。目前的研究结果表明，来自舌头和上腭的两种感觉模态的传入输入汇聚到臂旁核神经元上。
