Anxiety, Fear Learning & Neuroplasticity

Fear is learned when a cue reliably predicts something aversive, and it is reduced through extinction: new learning that the cue is now safe. Extinction does not appear to erase the original memory, which is why fear can return in new contexts or after time. This laboratory model informs exposure therapy without being identical to it.
