[Changes in the RNA concentration in neurons of the superior olivary complex in cats following monaural and binaural stimulation].

The nature of binaurally converging connections on the level of the superior olive nuclei was studied in cats anesthetized by the method of quantitative cytospectrophotometry. Significant increase in cytoplasmic RNA content in neurons of ipsi- and contralateral medial and lateral nuclei was observed after 2 hrs monaural stimulation nad 1.5 hrs binaural stimulation by rhythmical noise signals. The volume of functioning neurons of the nuclei studied was observed either to increase or not to differ from the control. The increase in RNA quantity both in ipsi-, and contralateral medial and lateral nuclei permits making the conclusion on the uniform distribution of binaurally converging connections on the neurons of these nuclei. Moreover, the data obtained enable us to assume that the accumulation of cytoplasmatic RNA occurs not only during excitation but also during inhibition.
