Delay cued and contextual fear conditioning—galanin-overexpressing transgenic mice. Performance of wild-type littermates (WT) and galanin-overexpressing transgenic mice (GAL-tg) in the standard delay cued and contextual fear conditioning experiment. (A) Freezing behavior during the first 2 min of training before CS–US presentation (Pre-US), and the final 2 min of the training session after CS–US presentations (Post-US). (B) Freezing behavior in the novel context 24 h after training, during the first 3 min of no CS presentation (Pre-Cue) and during the 3 min of CS presentation (Auditory Cue). (C) Freezing behavior 48 h following training, in the same context in which training was carried out on day 1. Data are presented as means ± SEM. No significant differences between genotypes were detected.
