Up-regulation of HuC gene expression in rat hippocampi after Morris
water maze training. Representative in situ
hybridization results are reported above for both the HuC and the
BRUNOL3 genes in naïve (NV), swimming control
(SW), and trained (TR) animals. Below, means ± SEM of the
densitometric determinations of the mRNA signal in the CA1, CA3, and
dentate gyrus (DG) subfields for six animals in each group (white bar,
NV; light gray bar, SW; black bar, TR;
****, P < 0.001, post
hoc analysis between SW and TR rats).
