Forgetting distracting memories is an active process in the brain of rats and humans
Selective amnesia: forgetting distracting memories - neuroscience short news

Both rats and humans use the prefrontal cortex for active forgetting. Forgetting is not a passive response, as many people think, and can be trained so a rat or a person can focus on things that are important to remember. Rats, for example, when repeatedly exposed to one of two familiar objects, forget that they have seen the other object in the past. In humans, active forgetting makes it possible to recall, for instance, where you parked your car without being distracted by other memories. Thus, remembering can cause forgetting, and this surprising finding could help us to understand about people’s capacities for selective amnesia.
