Zfp804a mRNA in MGN and TRN of thalamus. (A) Top, representative images of sagittal sections through the MGN. Bottom, image densitometry measures within the MGN through postnatal life show that Zfp804a expression in P86 adult rat is significantly lower than earlier P7 and P21 ages (Tukey's HSD, P<0.05). (B) Top, representative images of sagittal sections through the TRN. Bottom, image densitometry measures within the TRN show no significant changes across postnatal life. Scale bars: 4.0 mm.
