Deletion of STEP levels increases amygdala-dependent fear learning. Deletion of STEP levels increases amygdala-dependent fear learning. Animals hetero- or homozygous for the deletion of the STEP gene displayed greater conditioned suppression when presented with an auditory CS+ that had previously been associated with foot shock. Data shown is the average suppression ratio over the five CS+ presentations. ANOVA analysis identified a main effect of genotype (p ≤ 0.05) on conditioned suppression.
