Following injection of wheat germ agglutinin-conjugated horseradish peroxidase (WGA-HRP) into the pericruciate (sensorimotor) cortex on one side in the cat, we found labeled fibers surrounding the ventral horn of the spinal cord bilaterally, in addition to the crossed and the uncrossed lateral, ventral and dorsal corticospinal tracts (CSTs). These hitherto unknown fibers, which could be traced to the caudal end of the L2 segment, were predominantly contralateral to the WGA-HRP injection side. This study indicates the presence of newly recognized CST fibers in the cat.
在猫的一侧将小麦胚芽凝集素结合辣根过氧化物酶（WGA-HRP）注入十字周（感觉运动）皮质后，我们发现除了交叉和未交叉的外侧、腹侧和背侧皮质脊髓束（CSTs）外，双侧脊髓腹角周围有标记纤维。这些迄今未知的纤维可追踪到L2节段的尾端，主要位于WGA-HRP注射侧的对侧。本研究表明猫中存在新识别出的CST纤维。
