Does striated urethral sphincter activity alter urethral pressure during filling cystometry?
Urethral pressure does not increase during filling cystometry, despite increased activity of the striated urethral sphincter, which suggests that urethral pressure change does not reflect the integrity of the striated urethral sphincter.
Unlike neural stem cells in the cerebral cortex and spinal cord, which generate many neurons by repeated asymmetric division, cerebellar GCPs produce neurons predominantly by terminal symmetric division. These results indicate diverse mechanisms of neurogenesis in the mammalian brain.
