In normal group and sham lesion group, BDA positive neurons were distributed symmetrically in the pyramid cells of sensorimotor cortex, and BDA positive fibers of pyramid cells passed through the cerebral cortex, internal capsule, cerebral peduncle of midbrain, basilar portion of pons to the pyramid of medulla oblongata. At the lower part of the medulla oblongata, most of the BDA positive fibers passed through the pyramidal decussation to the contralateral side, continously descended at the ventral part of posterior funiculus just dorsal to the posterior gray commissure and ended at sacral spinal segments.

正常组和假损伤组大鼠BDA示踪显示BDA标记阳性细胞定位于双侧感觉运动皮层的锥体细胞，锥体细胞发出的BDA阳性纤维束对称分布于双侧皮层、内囊、大脑脚、脑桥基底部、延髓锥体中的皮质脊髓束内，继而经锥体交叉到脊髓后索，在双侧后索最深层、灰质后连合背侧下行至脊髓骶段。

The same results were observed in the brain of the unilateral pyramidotomy group above the level of the transection site. Below the level of the transection site, the BDA positive fibers were seen in the right pyramid of medulla oblongata and the left dorsal funiculus of spinal cord, but the BDA positive fibers in the left pyramid of medulla oblongata and the right dorsal funiculus of spinal cord were not seen.

锥体束横断损伤大鼠在损伤部位以上可见双侧对称的BDA阳性纤维束，损伤平面以下在右侧延髓锥体和左侧脊髓后索中见有BDA阳性纤维束，损伤侧锥体和右侧脊髓后索中未见有BDA阳性纤维束。

Results:(1) Spin-echo sequence included axial, coronal and sagittal images. In T1-weighted images,the medulla oblongata is isointense,the cistern is hypointense; in T2-weighted images,the medulla oblongata is isointense, CSF shows hyperintense, and the arteries of posterior fossa appear hypointense flow voids. The cisternal cranial nerves are not clearly demonstrated in the routine spin-echo images. In 3D-time of flight images, the brain tissue shows isointense, CSF is hypointense, the artery shows hyperintense,and the cranial nerves show linear isointense.

2，结果：(1)常规SE序列横断面、冠状面及矢状面T1WI显示延髓等脑组织呈等信号，延髓周围池脑脊液呈黑色低信号，T2WI显示脑组织为等信号、脑脊液为白色高信号，脑底动脉在池内高信号背景下由于&流空效应&而表现为低信号，常规序列由于成像参数关系而不能直接显示脑池内颅神经；三维时间飞跃(3D-TOF)成像序列显示脑组织为等信号，脑脊液为低信号，而脑池内脑底动脉则呈高信号、脑池内后组颅神经为线状等信号。
