室管膜下灰质异位(SEH)可以孤立的发生或伴有其他的神经或代谢性疾病。
Subependymal heterotopia (SEH) can occur in isolation or with other neurologic and metabolic disorders.
目的：对灰质异位进行运动功能的功能磁共振成像研究，探讨异位灰质的神经生理功能及功能磁共振成像在神经外科中的作用。
Objective: to study the the neurophysiology of heterotopic gray matter using functional MRI associated with motor task and the guidance function of fMRI in neurosurgery.
方法：以L 5脊神经结扎制备大鼠神经病理性痛模型，利用分离背根单纤维细胞外电生理记录异位放电。
Methods: Using L5 spinal nerve ligation as neuropathic pain model of rats, teased fiber recording technique was used to explore the property of ectopic discharges.
