Scientists from the University of Pennsylvania in the US found that remembering right and wrong differs depending on the type of electrical activity in a specific part of the brain (hippocampus). The results of the study were as follows: published In the journal Proceedings of the National Academy of Sciences (PNAS).
Remembering past events, experiences, or information tied to a specific context is called episodic memory. Episodic memory records events that occur during holidays, grocery shopping, or meeting certain people. These memories are recorded by the region of the brain called the hippocampus.
Scientists have found that before correcting a false (false) memory, a specific pattern of electrical activity occurs in the hippocampus. It is distinct from the type of activity that accompanies accurate recall of an event.
During the study, scientists asked participants to memorize strings of words consisting of animal or plant names. The words then had to be said correctly and in the correct order. During the experiment, researchers continuously monitored the participants’ brain activity. When the subject verbalized a series of words and misremembered a concept (for example, pronouncing “sunflower” instead of “lily”), the activity of his hippocampus was similar to the activity that occurred when pronouncing a completely unrelated word. given topic.
The authors hope that the study could be a step towards developing new techniques to combat memory-impairing diseases.
