|
• occasionally Purkinje cells have large clear vacuoles within their cytoplasm
|
• significant loss of the Purkinje cell population
|
• the dendritic arrays are abnormal
|
• numerous ectopic Purkinje cells are present in the molecular layer and occasionally in the granular layer
|
• shrinkage and gliosis of the molecular layer
