Autonomic ganglia have a population of small intensely fluorescent (SIF) cells with unknown function. We have investigated the afferent innervation of SIF cells in bullfrog sympathetic ganglia using intracellular recordings and light microscopy of stained preganglionic axon terminals. Contrary to previous knowledge, bullfrog SIF cells do indeed receive functional synaptic input and this innervation is provided solely by the C-type preganglionic nerve fibers.
自主神经节中有一群功能未知的小而强荧光（SIF）细胞。我们利用细胞内记录和染色的节前轴突终末的光学显微镜，研究了牛蛙交感神经节中SIF细胞的传入神经支配。与先前的认识相反，牛蛙SIF细胞确实接受功能性突触输入，并且这种神经支配仅由C型节前神经纤维提供。
