Studies in rodents have shown that it is possible to restore the brain’s access to forgotten memories. In the case of a person, this can be facilitated by persistent efforts to remember the truth on the tip of the tongue. Scientists talked about this issue in an article. Speech.
In one experiment, scientists trained rodents to associate something neutral (like a bell ringing) with something unpleasant (like a light blow to the leg). After several repetitions, the animals waited for a shock after the bell rang.
Scientists have found nerve cell circuits in the brain responsible for animals’ responses to sound. They then decided to test whether artificially activating these rodent cells could make them act as if they were expecting a kick to the foot, even if there was no bell or blow. They activated these cells using optogenetic stimulation. The experiment showed that it is indeed possible to activate such memories.
A similar process occurs in a person when a person cannot remember a fact but it is “on the tip of his tongue.” For example, if a person cannot remember the name of an acquaintance he met on the street. According to one hypothesis, this phenomenon may serve as a signal to the person that the information has not been forgotten but is not currently available, but persistent recall can make the desired memory accessible.
