Fear conditioning is "reinstated" in a person or a populace ((https://mondoweiss.net/2017/05/collective-traumatic-oppression/) "collective PTSD") upon re-exposure to-or the recall of-the fear-inducing stimulus.

(10,11) In previous studies, acute immobilization stress in mice significantly elevated hypothalamic pituitary adrenal (HPA) axis activity, resulting in impaired fear extinction and extinction retention following Pavlovian fear conditioning. (12,13) Furthermore, exposure to this stressor led to impaired long-term declarative memory and enhanced anxietylike behavior.

In addition, there was significant improvement in synaptic functions, as determined by long-term potentiation and contextual fear conditioning experiments, in association with the reversal of amyloid plaques.

Some assays (e.g., novel object location) are almost exclusively dependent on the hippocampus [45], while others (contextual fear conditioning or novel object recognition) also involve additional brain regions such as the amygdala and perirhinal cortex, respectively [45-47].
