Acute experiments on anesthetized and immobilized cats using extracellular derivation of neuronal responses and field potentials demonstrated the predominant localization of somatic (radial nerve) responses in the mediocentral and of visceral (splanchnic nerve) responses in the centrolateral regions of the ventral posterolateral thalamic nucleus. Both similarities and differences were found in patterns of neuronal responses to peripheral stimuli of different types. A quite high degree of convergence of somato-visceral impulsation was found in the central part of the nucleus compared with its medial and lateral regions. Predominance of comparatively long-latency convergent neurons over short-latency was observed. The inhibitory character of somatovisceral interaction and the more effective inhibitory influence of conditioning stimulation of the radial nerve on test-response of splanchnic origin were demonstrated.
在麻醉和固定的猫身上进行的急性实验，采用神经元反应和场电位的细胞外记录法，结果表明，丘脑腹后外侧核中央内侧区域主要记录到躯体（桡神经）反应，而中央外侧区域主要记录到内脏（内脏神经）反应。不同类型外周刺激诱发的神经元反应模式既有相似之处，也有不同之处。与内侧和外侧区域相比，在该核的中央部分发现了相当高程度的体-内脏冲动汇聚。观察到相对长潜伏期的汇聚神经元比短潜伏期的更占优势。证明了体-内脏相互作用的抑制特性，以及桡神经条件刺激对内脏神经源性测试反应的抑制作用更有效。
