Analysis of the brain positron emission tomography data using 18F-ФДГ during the processes of neurophysiological control of the lower urinary tract function

During the last few years the role of the brain centers in the regulation and control of the micturition is 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 areas the 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 phase a standard activity of the brain was denoted with light dominant of 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 by the posterior regions of the cortex, which provide a sympathetic dominant. Bladder emptying is regulated via the anterior regions, which have parasympathetic influence on the internal organs. A significant role was also shown for cingulate gyrus during the physiological regulation of micturition.
