[Synaptic organization of the vestibular nucleus in the medulla oblongata of the frog Rana temporaria].
Studies have been made on the synaptic organization of ventral vestibular nucleus of the frog R. temporaria. Besides numerous axo-somatic and axo-dendritic synapses, 3-component axo-axonal synaptic contacts were revealed which indicate a possibility of presynaptic inhibition in the nucleus studied. Three types of membrane specializations were found in axo-somatic and axo-dendritic synaptic contacts-active zone of chemical synapse, symmetric thickening of the membranes of desmosomal type and close linking of the membranes of electrotonic synapse. Functional role of the observed contacts is discussed.
