Their shapes were diversiform such as triangle spherical, nummular, elliptic and fusiform etc.They had one or several tuber.The immunopositive fibers were strings of pearls,and crossed each other. This experimentation results showed that development level of nNOS immunopositive neurons approach the adult rabbit when it is a young rabbit. The effete change appears when rabbits turn ageing.That was expression intensity weaken.

nNOS阳性神经元呈棕褐色，着色主要位于胞浆内，细胞核处染色较为浅淡；神经元胞体形态多种多样，有三角形、圆形、椭圆行、梭形等多种形状，神经元突起有一个或者数个；nNOS阳性纤维大多呈棕色串珠样，有些区域nNOS阳性纤维交错分布，相互交织成网状。
