Cytoplasmic organelles in neurons of the dorsal lateral geniculate nucleus of aged rats.
The ultrastructural characteristics of the neurons containing complex convolutions have been studied in the dorsal lateral geniculate nucleus of the 31-month-old rat. Neurons were seen to contain oval or round dense bodies which were surrounded by a nuclear membrane and granular endoplasmic reticulum. Their perikarya showed rarely clusters of pleomorphic and small clear vesicles intermingled with a few larger vesicles of dense material. Dendrites occasionally exhibited intermediate forms between laminated bodies and complex convolutions. The significance of these features has been discussed.
