OBJECTIVE
To explore the reorganization of brain cortex on spinal cord injury (SCI) patients with functional magnetic resonance imaging (fMRI) techniques and elucidate its recurring patterns so as to provide theoretic rationales for SCI treatment.
METHODS
We designed different tasks for 9 SCI patients and 10 normal subjects. The tasks were named block design and it was divided into rest period (R) and stimulating period (S). All subjects underwent fMRI scan while they were performing the tasks.
RESULTS
A significant reorganization occurred on brain cortex of SCI patients after spinal cord injury. This phenomenon changed with elapsing time after spinal cord injury.
CONCLUSION
Brain cortex undergoes reorganization after spinal cord injury, especially primary sensory and motor cortex.
目的
运用功能磁共振成像（fMRI）技术探究脊髓损伤（SCI）患者脑皮质的重组情况，并阐明其复发模式，为脊髓损伤的治疗提供理论依据。
方法
我们为9名脊髓损伤患者和10名正常受试者设计了不同的任务。这些任务被称为组块设计，分为静息期（R）和刺激期（S）。所有受试者在执行任务时均接受功能磁共振成像扫描。
结果
脊髓损伤后，脊髓损伤患者的脑皮质发生了显著重组。这种现象随脊髓损伤后的时间推移而变化。
结论
脊髓损伤后脑皮质会发生重组，尤其是初级感觉和运动皮质。
