title: [Types of organization of interneuronal contacts in the ventral horn of the cat spinal cord].
abstract: The ultrastructure of intermediate neurons of the ventral horn of the spinal cord of cats was studied. It has been established that interneuronal contacts having different structural organization may be grouped according to the principle of different space distribution of pre- and postsynaptic elements. Contacts of the first type realize convergence of different synaptic effects on one post-synaptic structure. In contacts of the second type the synaptic action of the axon fibre or a terminal diverge to different elements of the neuropile. Several synaptic forms of contacts of the second type were revealed. The role of the above structures in the physiological activity of intermediate neurons of the spinal cord is discussed.
