Human cerebral cortex is thinnest at 8wks of intra–uterine life and becomes thicker progressively along the supero–lateral and infero–lateral walls from frontal to occipital poles. brains of 50 still born human foetuses of both sexes were procured and 5mm tissues bits of frontal, temporal, parietal and occipital cortices were processed for histological examination using crystal violet stained.the neurons were granular until 18wks of gestation and showed few pyramidal cells at 24 weeks and than sesqulaminar pattern with predominance of Betz cells in frontal and temporal cortex and predominance of granule cells in parietal and occipital cortex.  Cell migration and genesis is important in disorders like epilepsy or dyslepsy.
