GLYCOLYSIS IN THE PARTS OF THE CENTRAL NERVOUS SYSTEM OF CATS AND DOGS DURING GROWTH

Abstract

Glycolysis in the C.N.S. has been studied in dogs and cats at various stages of their development. In the newborn" glycolysis is most rapid in the medulla, slower in cephalad and caudad regions. In the adult, the highest rates are in the caudate nucleus and cerebral cortex, with lower rates in each succeeding caudad portion of the neuraxis. Glycolysis of the medulla and cord decreases progressively with age. In all regions lactic acid formation rises to a maximum at some time during development and then recedes in later life. In general, that part of the brain exhibiting the highest glycolytic rate advances in a rostral direction as growth proceeds.
