— Developmental changes of the 2′,3′‐cyclic nucleotide 3′‐phosphohydrolase activity in the chick brain and spinal cord are reported. The greater part of increase in enzyme activity occurred between 18 days of incubation and 3 days after hatching in the whole brain, and between 18 and 21 days of incubation in the spinal cord. These periods are those of active myelination in the chick brain and spinal cord, respectively. The possibility was emphasized that 2′,3′‐cyclic nucleotide 3′‐phosphohydrolase can be used as a marker for the myelin sheaths in the developing central nervous system. Comparisons were also made among the developmental changes in the forebrain, midbrain, brain stem, cerebellum, and spinal cord.
