[Cellular organization of the vestibular nucleus of the frog medulla oblongata].
Ventral vestibular nucleus of frogs is composed by multipolar cells of isodendritic type. Three basic kinds of cells are found in the nucleus-large, medium and small ones which differ mainly by the number of synaptic contacts on their perikaryon. The neuropile of the vestibular nucleus contains a large number of unmyelinated nervous fibers and exhibits numerous contacts formed along each of the fibers. Similar features in the organization of ventral vestibular nucleus in frogs and Deuters nucleus in rats and cats are noted. Functional role of cellular elements composing the nucleus is discussed.
