Following large injections of horseradish peroxidase into the thalamus of the adult rat, labeled neurons can be detected in the contralateral principal sensory nucleus and the subnucleus interpolaris of the spinal trigeminal nucleus. Thalamic projection neurons in the principal sensory nucleus are arranged in discrete aggregates which replicate the organization of the vibrissae and other parts of the face. This cellular organization corresponds very well with the pattern of vibrissae related afferent termination in this region of the nucleus as seen in SDH preparations. There is no such cellular organization in the subnucleus interpolaris.
在成年大鼠丘脑内大量注射辣根过氧化物酶后，可在对侧的主要感觉核和三叉神经脊束核的极间亚核中检测到标记神经元。主要感觉核中的丘脑投射神经元呈离散的聚集排列，与触须及面部其他部位的组织结构相对应。这种细胞组织与在琥珀酸脱氢酶（SDH）制剂中所见的该核区域内触须相关传入终末的模式非常吻合。极间亚核中不存在这样的细胞组织。
