nOL training at PN17 leads to a significant increase in the GluN2A/GluN2B ratio in the dorsal hippocampus. Examples and densitometric Western blot analyses of dHC total extracts obtained from rats trained in nOL at PN17 (gray bar) and euthanized 24 h after training. Controls animals were habituated and exposed to the arena, without objects, and euthanized at the matched time point. Data are expressed as mean percentage ± SEM of control rats. N = 9/group. Unpaired two-tailed Student's t-test (*) P < 0.05, (**) P < 0.01.
