Cum știe creierul tău că ai renovat casa, fără să șteargă amintirea veche? Secretul „gardienilor” din hipocamp

A recent study reveals that specific neurons in the hippocampus protect existing memories while allowing new information to be integrated. This mechanism, identified by Spanish researchers, involves the dentate gyrus, which helps manage memory retention. Experiments on mice showed that varying levels of inhibition affect memory recall and detail. The findings suggest that the hippocampus can either facilitate new information incorporation or strengthen existing memories based on contextual importance.
