The nucleus lateralis tuberis (NLT) of fishes was studied light- and electron microscopically. In the carp, the ventromedial cells of the nucleus send processes into the lumen of the 3rd ventricle where they form strikingly large, club-shaped liquor contacting nerve endings built up of an inner and outer zone. Smaller neurons situated between the cells of the NLT, form small, ciliated, free, dense-core vesicles containing nerve endings in the cerebrospinal fluid. The outer zone of the liquor contacting terminals of the NLT contains an extraordinarily well developed endoplasmic reticulum which flat, rough cisternae run parallel to the surface of the terminal. In the inner zone of the nerve ending, Golgi areas and numerous mitochondria can be observed besides of scattered endoplasmic cisternae. The terminal contains neurosecretory granules (1,300-1,900 Å) of various amounts, and some neurotubules. Furthermore, in the lumen of the 3rd ventricle, there occur neurites containing catecholamine granules. These axons form repeatedly synapses with the liquor contacting terminals of the NLT. The presynaptic cytoplasm is characterized by synaptic (400-550 Å) and densecore vesicles (600-800 Å). Similar synapses occur on the neurosecretory perikarya and their processes. The extensive Golgi region of the perikarya of the NLT shows equivalents of secretory activity. On the basis of the morphological data, the part of the NLT situated near the ventricle is considered as to belong to the liquor contacting neuronal system. The presumable significance of the liquor contacting nerve endings of the NLT is discussed.
