The brain glycogen of the control guinea-pig and of those electrically stimulated once per day for 10 days were observed histochemically with lead-tetra-acetate-SCHIFF method. The animals were perfused with ORTH's fluid one or 10 days after the last stimulation.
In the neocortex marked increases of very fine granules were observed in the lamina zonalis and the intercellular neuropil of the deeper layers. On the other hand, in the brain stem the substantia nigra, nucleus ruber and corpus trapezoides showed the definitely increased glycogen content. The changes in the allocortex, basal ganglia, diencephalon and cerebellum were not prominent.
