There were nerve fibers distributing along nerve cords but no neuron in the nerve trunk and nerve cords. 神经干及神经索中无神经元胞体,仅有沿神经索方向分布的神经纤维。
The common pathological changes in epileptic focus are ( use the hippocampus as an example): neuron degeneration, death, lesions of the distributing of neuron dendrite, demission of synapse spine, proliferation of glia, and axon spouting of hippocampal granular cells. 由于癫痫病灶最常见的病理变化(以海马区为例)是神经元变性、坏死,未死亡神经元树突分布范围的缩小和突触棘的消失,胶质细胞增生以及海马颗粒细胞的轴索发芽等。
