During the last few years the role of the brain centers in the regulation and control of the intensively discussed. It was shown, that cortical center in charge of the micturition control is paracentral lobule on the medial surface of the hemisphere. During the excitation of the supracalleous part of the brain, it’s cingulate and orbital inhibitory effect on the bladder is evident. The influence of the anterior cingulate region on the micturition activation was also evident.

Our study is devoted to the study of the positron-emission tomography (PET) changes in the process of the neurophysiological control of the micturition. During the physiological storage and continence standard activity of the brain was denoted with light the left hemisphere. In process of micturition the was a rise in the summary brain activity over the mean detected level, which appeared to be statistically significant. The study showed that storage phase of the micturition is controlled posterior regions of the cortex, which provide a sympathetic dominant. Bladder emptying is regulated via the anterior regions, parasympathetic influence on the internal organs. A significant role was also shown for cingulate gyrus during the physiological micturition.
