Four temporal bones of human newborns were studied with light and electron microscopy. In contrast to the adult human spiral ganglion as described by Kimura and coworkers, that of the newborn baby shows no myelination, either of the large ganglion cells or of the small. Whereas in adults the small ganglion cells contain neurofilaments or neurotubules, newborns have no cytoplasmic criteria by which to differentiate large and small neurons. Except for the small neurons, unmyelinated nerve fibers end on the surface of the ganglion cell or they penetrate into the cytoplasm. They form synaptic contacts. It is assumed that they belong to the efferent intraganglionic spiral bundle.
对4例人类新生儿的颞骨进行了光镜和电镜研究。与Kimura及其同事所描述的成人人类螺旋神经节不同，新生婴儿的螺旋神经节无论是大神经节细胞还是小神经节细胞均无髓鞘形成。在成人中，小神经节细胞含有神经丝或神经微管，而新生儿则没有可用来区分大、小神经元的细胞质标准。除小神经元外，无髓神经纤维终止于神经节细胞表面或穿入细胞质。它们形成突触联系。据推测，它们属于神经节内传出螺旋束。
