Abstract The development and distribution of + ‐K + ‐stimulated and Mg 2+ ‐dependent ATPase activity in different parts of the chick embryo brain were investigated. Maximal changes in the Na + ‐K + ‐stimulated ATPase activity in the hemispheres and optic lobes took place between day 15 and 17 and in the cerebellum and brain stem between day 17 and 19 of incubation. Most of this activity was localized in the membranous fraction of the chick embryo brain. An attempt was made to correlate the rapid rise in the activity of this enzyme with the development of electrical properties of the chick embryo brain.
