title: Stumbler, a new mutant mouse with cerebellar disease.
abstract: A new mutant mouse named Stumbler (stu) displays clinical features suggesting a cerebellar lesion. The main light microscopic findings, based on a Golgi technique and on sections of plastic embedded material, are that Purkinje cells in the mutant cerebellum have small dendritic arborizations and exhibit immature spines on their somata. Purkinje cells also contain an increased number of mitochondrial profiles both in cell bodies and in swellings on dendrites.
