Vesico-Motor Areas in the Cat Midbrain

KURU and OZAKI11) (1959) demonstrated the existence of vesico-motor centers in the medulla oblongata in cats.The medullary vesico-motor centers are cornposed of two antagonistic centers, namely the vesico-constrictor and vesico-relaxer centers.The former is situated in the ventro-lateral reticular formation and the latter in the dorso-medial reticular formation (TOKUNAGA and KURU19) 1959).Previous to these investigations, the existence of supraspinal micturition facilitatory and inhibitory areas had been reported in the hypothalamus (KARPLus and KREIDL9) 1909, LICHTENSTERN16) 1912, BEATTIE and KERR4) 1936, KABAT, tentorium by occipitoparietal craniotomy.By retracting the occipital lobe anterolate-
