The influence of age on supraoptic nucleus neurons of the rat: morphometric and morphologic changes.
Neurosecretory neurons (NSNs) of the supraoptic nucleus of 2-year-old rats presented significantly greater nuclear volumes and nuclear perimeters than those of 3-month-old animals. In aged NSNs, membranous bodies (MBs) were observed in the cytoplasm and the cell nucleus. The possible origin and function of these MBs are discussed.
