nervous system

abnormal neuron morphology ( J:30435 )

• less than 1% of neurons in cerebral cortex were ballooned at 60 days of age

• contained secondary lysosomes containing poorly defined lamellar structures and lipofuscin like material

• 10% of neurons in neocortex were ballooned by 150 days of age and contained dense vacuoles in cytoplasm
