the region of the cerebellum was x-irradiated in infant rats with selected exposure schedules designed to produce animals in which the cerebellar cortex was ( a ) essentially normal except for agenesis of late forming granule cells with axons situated in the uppermost molecular layer ( 12 -- 15x ) , ( b ) lacking in stellate cells , with a severe reduction in granule cells with axons in the upper molecular layer ( 8 -- 15x ) , ( c ) morphologically disorganized but had only intermediate cell agenesis ( 4 -- 5x ) , or ( d ) disorganized and devoid of practically all postnatally forming interneurons ( 4 -- 15x ) .
