Fig. 2. Dose-dependent histone H3 phosphorylation. Mice were injected with 5 mg kg^–1, 1 mg kg^–1 or 0.2 mg kg^–1 SKF82958, 300 mg kg^–1, 100 mg kg^–1 or 30 mg kg^–1 pilocarpine, or 35 mg kg^–1, 20 mg kg^–1 or 10 mg kg^–1 kainic acid, and sacrificed after 1 hour. Control animals, indicated with the symbol (–) were injected with saline solution. A portion of the DG is shown. Scale bar, 70 µM.
