Social fear conditioning (SFC) induces social fear. (a) Pre-conditioning investigation of the non-social stimulus (empty cage) during SFC on day 1 shown by the unconditioned control (SFC−) mice and conditioned socially fearful (SFC+) mice. Cohort 1 represents the mice used for the immunohistochemistry study (n = 9 SFC−; n = 10 SFC+), whereas cohort 2 represents the mice used for the gene expression study (n = 10 SFC−; n = 10 SFC+). (b) Investigation of the social stimulus during social fear assessment on day 2. Data represent means + SEM. Statistical analysis was performed using a two-sample comparison test; p *** < 0.001.
