摘要: Abstract The development of cerebral hemispheres was quantitatively studied in twenty 15-day-old rat fetuses from two litters. Thicknesses, areas and mitotic counts (per mm length ependyma) were not different for left right (parasagittal paraffin sections). On the other hand, among individual same litter, differed as much 2 standard deviations, these values correlated with fetal weights (age). It appears that litter age may differ extent their brain development.
