The majority of somatosensory neurons recorded from the mesencephalic parabrachial area and pontine parabrachial nucleus of the cat responded exclusively to noxious mechanical stimuli to the skin. Their receptive fields were very large. Two-thirds of the neurons tested responded to electrical stimulation of the tooth pulp. These results suggest that neurons in this area have extensive convergence of spinal and trigeminal inputs, and contribute to the affective or autonomic aspects of pain.
在猫的中脑臂旁区和脑桥臂旁核记录到的大多数体感神经元仅对皮肤的伤害性机械刺激有反应。它们的感受野非常大。三分之二接受测试的神经元对牙髓的电刺激有反应。这些结果表明，该区域的神经元具有脊髓和三叉神经输入的广泛汇聚，并参与疼痛的情感或自主神经方面。
