Figure 2

Doublecortin-immunoreactive (DCX+) cells in different cortical areas from Pb exposure and age-matched control groups surviving 2 months. Left panel images show parietal (A), temporal (C) and frontal (E) cortices from a control animal. Right panel images (B, D, F) show images from comparable regions in a Pb-treated animal. Inserts show closer view of the labeled cells, with arrows pointing to medium to large sized, and small sized cells. Overall, the amount and morphology of DCX + cells appear to be comparable between the two groups. Scale bar in panel A = 200 μm applying to main panels, equivalent to 100 μm for enlarged inserts.
