Proactive modulation of fear conditioning after exposures to fearful and non-fearful models. (A) The NF group exhibited a significant reduction of fear when compared to all other groups. This was not due to latent inhibition as revealed by similar freezing levels among the No-PE, Box and TM groups. Statistically significant differences: ***p < 0.001, NF vs F, No-PE, Box and TM groups. (B) Two brief trials of social interactions were required for modulation of fear in the NF but not (C) F groups of mice when compared to TM controls.
