刺激A、B和C行的触须肌可增加三叉神经脊束核尾侧部(Sp 5c)的(14 C)2-脱氧葡萄糖(2DG)摄取,主要位于III-IV层的腹侧部分,II和V的激活较少。刺激触须上方的普通皮毛主要激活II层,深层激活较少。激活的模式是兼容的倒置头,洋葱皮Sp 5c躯体。将小麦胚芽凝集素-辣根过氧化物酶(WGA-HRP)注射到触须肌行A-B和B-C之间的普通被毛中,仅导致Sp 5c的顺行跨神经节标记,主要是II层,V层标记较少,III和IV层标记非常稀疏。WGA-HRP皮肤注射似乎主要标记小纤维,其沿着较大纤维,在常见被毛刺激期间代谢活化。
Stimulation of mystacial vibrissae in rows A, B, and C increased (14C) 2‐deoxyglucose (2DG) uptake in spinal trigeminal nucleus pars caudalis (Sp5c) mostly in ventral portions of laminae III‐IV with less activation of II and V. Stimulation of common fur above the whiskers mainly activated lamina II, with less activation in deeper layers. The patterns of activation were compatible with an inverted head, onion skin Sp5c somatotopy. Wheat‐germ Agglutinin‐Horseradish Peroxidase (WGA‐HRP) injections into common fur between mystacial vibrissae rows A–B and B–C led to anterograde transganglionic labeling only of Sp5c, mainly of lamina II with less label in layer V, and very sparse label in III and IV. WGA‐HRP skin injections appear to primarily label small fibers, which along with larger fibers, were metabolically activated during common fur stimulation.
