While applying natural stimulation to the entire oral cavity, we recorded responses from 489 neurons (400 mechanoreceptive, 84 taste and 5 cold neurons) in the insular cortex of urethane-anesthetized rats. Intermingled with the mechanoreceptive neurons was a major group of taste neurons located in the granular or dysgranular insular area at levels of 2.55-1.20 mm anterior to the bed nucleus of the anterior commissure as stereotaxically located. Most of the taste neurons were also sensitive to mechanical stimulation of the oral and/or perioral tissue.
在对整个口腔施加自然刺激时，我们记录了经乌拉坦麻醉的大鼠岛叶皮质中489个神经元（400个机械感受神经元、84个味觉神经元和5个冷觉神经元）的反应。与机械感受神经元混合在一起的是一大组味觉神经元，它们位于前连合核床前方2.55 - 1.20毫米水平的颗粒状或颗粒减少的岛叶区域，这是通过立体定位确定的。大多数味觉神经元对口腔和/或口周组织的机械刺激也敏感。
