Abstract:
Objective The ultrastructure of the distal CSF-contacting neurons in the dorsal raphe and the relationships with their surrounding tissues were observed and a new morphological evidence for their functional significance was offered. Methods We combined CB-HRP tracing with electron microscopic techniques and observed the ultrastructure of the distal CSF-contacting neurons in the dorsal raphe and the relationships with their surrounding tissues. Results 1.The CSF-contacting neurons have the general cytological structure of neurons; 2.CB-HRP mainly is localized in the trans face of the Golgi apparatus and lysosomes;3.There are two kinds of contrary direction synaptic relationships between the distal CSF-contacting neurons and the non-CSF-contacting neurons.Conclusions 1.There are no obvious differences between the CSF-contacting neurons and other neurons in ultrastructure;2.The Golgi apparatus and the lysosomes may exist the special function in take and transport the material from CSF;3.The CSF-contacting neurons can not only transport the material or deliver the information from the dorsal raphe to CSF,but also from CSF to the dorsal raphe.
