Effect of chronic Pb exposure on dendritic length in rat brain was subject to brain regions×age×gender age interaction.

<p>Dendritic length in male hippocampal neurons at PND30, PND60, PND90, respectively (A). Dendritic length in male mPFC at PND30, PND60, PND90, respectively (B). Dendritic length in female hippocampal neurons at PND30, PND60, PND90, respectively (C). Dendritic length in female mPFC at PND30, PND60, PND90, respectively (D). Data are expressed as mean ± SEM. *P<0.05, ***P<0.001. n = 8 per group.
