Behavioral stimulation results in upregulation of Tbr1 and Grin2b in adult brains. (A) A simple flowchart of CTA test. The tissues were sampled 2 and 24 h after injection. (B) The amounts of water drunk during pre-training (D-1) and sucrose drunk on the CTA training day (D0). (C–E) Quantitative-PCR analyses to examine the expression of Tbr1, Grin2b, and c-Fos upon behavioral training. Two hours after NaCl or LiCl injection and 24 h after LiCl injection, the lateral amygdala, insular cortex and ventral hippocampus were collected for quantitative-PCR using Cyp as an internal control to detect the relative mRNA levels of Tbr1 (C), Grin2b (D), and c-Fos (E) in adult mice. Six animals were used for each experiment. All data represent the mean + SEM. *P < 0.05; **P < 0.001; ***P < 0.001; n.s., not significant.
