| Research Abstract |
The patients who had severe symptom of Minamata disease and, in the case that an extrapyramidal sign was observed clinically, showed pathological changes in the extrapyramidal tract nuclei. In addition, pathological changes were observed in the extrapyramidal tract nuclei in the case that whole brain was damaged severely. The methylmercury treated mice displayed locomotor hyperactivity. Histopathological examination showed significant decrease in the number of neurons with proliferation of astroglias in the bilateral caudate putamen in the methylmercury treated mice.
