The aim of the present study was to determine the somatotopy of the sensory innervation of the rat hindlimb at the level of the dorsal root ganglia (DRGs) during the fetal and postnatal period. Injections of wheat germ agglutinin-horseradish peroxidase (WGA-HRP) were made into the hindlimb of fetal and postnatal rats. These injections result in completely and partially labeled DRGs. Partial labeling always concerns the rostral or caudal half of a DRG. Using half DRGs as subsegmental units, a description is given of a somatotopic organization of the sensory innervation of the rat hindlimb during development.
本研究的目的是确定胎儿期和出生后大鼠后肢感觉神经支配在背根神经节（DRG）水平的躯体定位。将小麦胚芽凝集素-辣根过氧化物酶（WGA-HRP）注射到胎儿期和出生后大鼠的后肢。这些注射导致DRG完全和部分标记。部分标记总是涉及DRG的头侧或尾侧半部。以半DRG作为亚节段单位，描述了大鼠后肢感觉神经支配在发育过程中的躯体定位组织。
