Summary The ultrastructural aspects of the paraventricular nucleus and its neuropil are described in the normal rat. Two types of neurons can be distinguished morphologically. The first type contains numerous dense-core vesicles (mean diameter: 140 nm). The cisternae of the endoplasmic reticulum are arranged parallely at the periphery of the cell body. The second type of neuron contains a few dense-core vesicles (mean diameter: 75 nm) and the endoplasmic reticulum is randomly distributed in the cytoplasm. In the neuropil, two types of dense-core vesicles are observed in separated axons. The histogram of the distribution of their mean diameter clearly indicates a double population of vesicles. The signification of the second type of neuron in the paraventricular nucleus is discussed and its possible relation to TRF synthesis is evoked.
