Scanning electron microscopy of the third ventricular wall of the arctic lamprey, Lampetra japonica, revealed the occurrence of supraependymal neurons in several regions of the ventricular surface. These neurons--as varicose fibers of various calibers--traversed among the cilia, microvilli, and bulbous protrusions of the ependymal surface. Occasionally synapse-like contact were found between these nerve fibers and the intraventricular processes of the cerebrospinal fluid (CSF)-contacting subependymal neurons in the hypothalamus. A possible function of the supraependymal neurons is discussed in relation to the hypothalamic neuroendocrine system.
