Alteration in the number of neuronal cells in the PrL of adult female mice born to dams that were administered NaAsO₂. (A) Illustration of the region of interest, the PrL, adapted from a mouse brain atlas (Franklin and Paxinos, 2008). (B) Representative photomicrograph of the PrL in Golgi- and Cresyl Fast Violet-stained coronal brain sections. The Greek numbered (I–VI) regions indicate the cortical layers of the PrL. Scale bar = 20 μm. (C) Photomicrographs of the PrL at high magnification showing a Cresyl Fast Violet-stained pyramidal neuron (P), a non-pyramidal neuron (NP), and a glial cell (G). The length of scale bar indicates 5 μm. The number of pyramidal neurons (D), non-pyramidal neurons (E), and glial cells (F) in the PrL. Values are expressed as mean ± SEM (control group n = 7, NaAsO₂-exposed groups n = 5). An asterisk indicates p < 0.05 vs. the control group.
