用辣根过氧化物酶溶液浸泡大鼠前肢周围神经残肢。正中神经、尺神经、桡神经和肌皮神经的浸渍显示，每条神经在楔形核中都有明确的投影区。桡神经在外侧楔状核和沿主楔状核背缘的窄带上投射很重。桡深神经和桡浅神经的染色显示，它们分别严重投射到外侧和主楔形。尺神经和正中神经主要投射到主楔状核的内侧和外侧部分，桡神经末梢野的腹侧。主楔形核的吻侧和尾侧可以通过细胞结构特征和末端纤维取向来区分。
Stumps of rat forelimb peripheral nerves were soaked in horseradish peroxidase solution. Impregnation of the median, ulnar, radial and musculocutaneous nerves revealed that each nerve had definite projection zones in the cuneate nuclei. The radial nerve projected quite heavily to the lateral cuneate nucleus and to a narrow band along the dorsal edge of the main cuneate nucleus. Staining of the deep radial and superficial radial nerves showed that they projected heavily to the lateral and main cuneate, respectively. The ulnar and median nerves projected primarily to medial and lateral portions of the main cuneate nucleus, ventral to the terminal field of the radial nerve. The rostral and caudal portions of the main cuneate nucleus were discriminable by cytoarchitectural characteristics and by terminal fiber orientation.
