Summary
The areas of molecular and granular layers in four large cerebellar cortical dysplasias were measured with the planimeter and the Purkinje cells were counted. There was a relative deficit of molecular layer and a still greater deficit of Purkinje cells in three of the four dysplasias. The fourth one had normal numbers of Purkinje cells per molecular layer and a relative deficit of granular layer. These abnormal proportions in the composition of a dysplasia may relate to the timing of its origin.
