Rats born to malnourished mothers have a reduction in overall brain weight and DNA content that is more marked in the cerebellum than in the cerebrum. I 10 DNA content is an indicator of tissue cellularity, and microscopic examination of the cerebellum shows a 44% decrease in glial cells and 13% decrease in neurons. 110 Rat pups born to mothers fed a 5% protein and low-calorie diet have a 50% decrease in body size and up to 40% reduction in brain weight. II I Glial cell number is reduced by 50% in the corpus callosum and in ascending spinal sensory tracts.
