Quantitative analysis of density of AhR mRNA signals in the hippocampal subregions in 7-day and 12-week old. Punctate density of AhR mRNA signals in the CA1, CA3, and DG in the hippocampus. Signal density in the CA1 and CA3 pyramidal cell layer (Py) and DG granule cell layer (Gr) was dramatically higher than that in the stratum oriens (SO) and stratum radiatum (SR) of CA1 and CA3, and hilus (Hi) of DG in 7-day- and 12-week-old mice. Signal density in the Py and Gr in 12-week-old mice was significantly increased when compared with that in the 7-day-old mice. ∗∗ and ∗∗∗ indicate significant difference between the subregions (p < 0.01 and 0.001, respectively). ## indicates significant difference between ages (p < 0.01). The values are shown as mean ± SEM for three mice/age.
