Abstract: | The neuropathologic findings of the Wistar ataxic rat brain were reported after making serial sections of the brain and studying the cerebellum with an electron microscope. Twenty-five adult Wistar rats from a mutant strain were used: 14 were ataxic and 11 were normal. In the brains of the Wistar ataxic rats, neuropathologic abnormalities were present only in the Purkinje cells. The possibility of a new model animal with autosomal recessive cerebellar ataxia is discussed. |
