Pontine urine storage center in the dog.
Electrical stimulation of the presumptive pontine urine storage center, areas ventral to and/or lateral to the pontine micturition center, elicited an increase in threshold volume at which reflex micturition occurred in response to bladder filling with physiological saline, suggesting a facilitatory effect on the urine storage function. The electrolytic lesions made in the stimulated areas were histologically identified to distribute at the nucleus reticularis pontis oralis, Kölliker-Fuse nucleus and subcoeruleus. These nucleus seemed to work as a pontine urine storage center and to perform a reciprocal action with the pontine micturition center.
