title: [The influence of synaptic processes on changes in neuronal structure].
abstract: Reactions of the spinal motoneurons to the afferent inflow were different in frogs: some neurons generated spike potentials during 10-min rhythmic stimulation (1/sec) of afferents, other neurons were switched on and off. The motoneurons and their synapses increased in size, their cytoplasmic matrix became lighter and ribosoms deteriorated. Antidromic activation did not entail modofocation of size or color of the cells. RNP granules were safe and local organellas degenerated. The role of synaptic processes in regulation of RNP metabolism and in intracellular reparation, was revealed.
