Detection of neuronal activity associated with function of lower urinary tract with use of functional magnetic resonance imaging
 Holý, Petr ; Zachoval, Roman (advisor) ; Hanuš, Tomáš (referee) ; Mašata, Jaromír (referee)
of the thesis Considerable research attention has been paid to the neural regulation of the lower urinary tract (LUT) in past three decades. The aim of this work is mapping of a brain activity by functional magnetic resonance imaging (fMRI) using refined scanning protocol with synchronously performed urodynamics. We aimed to detect neural activity associated with pelvic floor muscle (PF) contractions, filling of urinary bladder and miction. In addition we evaluated using fMRI brain activity associated with urinary bladder filling in patients with a complete spinal cord injury (SCI). We hypothesized activation of brainstem and forebrain areas in receiving information from the vagal nerves. Adjustments of urodynamic system enabled successful implementation of synchronous filling cystometry with fMRI evaluation of cortical activity. We concluded that synchronous urodynamic examination is a novel feasible method that facilitates and enhance interpretation of fMRI data acquired. The main clusters of brain activation during PF contractions were observed in the medial surface of the frontal lobe (primary motor area) and supplementary motor area (SMA). We detected neural activity associated with filling of urinary bladder and miction in middle and inferior frontal gyrus, angular gyrus, posterior and...
