Line graphs showing the extent of reduction (% of control levels) of smaller (blue) relative to larger (purple) doublecortin-immunoreactive (DCX+) cells in Pb-treated guinea pigs over the parietal (A), temporal (B), frontal (C) and occipital (D) cortices surviving 2, 4 and 6 months. Statistic differences exist between of the two cell groups at 4 and 6 months surviving points in all analyzed areas. #: p<0.05; *: p<0.01.
