| Abstract: | The innervation of the urinary bladder was studied in 40 rabbits, 5 of which were control and in 35 animals the posterior and anterior nuclei of the hypothalamus were stimulated by electric current through bipolar electrodes. The efferent innervation connections in whose terminal plexuses there occurred absorption of catecholamines were shown histochemically and neurohistologically to be involved in the pathological process. Reactive and degenerative changes were found to take place in receptory nerve terminations, and first of all in free ones. Then the bodies of pseudounipolar neurons of spinal ganglia were changed. Changes were also found in the connections of sensory neurons with the cells of Goll's and Burdach's nuclei. |
