mRNA levels of ERK1 and ERK2 in frontal cortex (FC) (a) and hippocampus (b) of TC, non-LH, and LH rats. Data are the mean ± SD from 6 animals in each group. Overall group differences in the 3 groups are as follows. ERK1: FC, , , and ; hippocampus, , , and . ERK2: FC, , , and ; hippocampus, , , and .
