Nouvelle traduction : Cerveau : comprendre les mécanismes de la mémorisation

The researchers demonstrated that images seen only a few seconds are memorized by the human brain and can be recognized ten years later

To remember the name of former classmates 50 years after leaving the school or the title of the favorite broadcast programs of our childhood, these are only some examples of the incredible capacities of our memory.

Ten years after, they remembered Researchers of CERCO (TOULOUSE III CNRS / UNIVERSITY - Paul Sabatier) called back participants whom had been tested in the laboratory approximately ten years ago, in order to test again their memory. The obtained results show that images seen a few seconds can be recognized decade later. These works are available on-line since November 5th, 2017 in the newspaper Cognition.

A new form of memorization

In the conditions of the experiment, it thus seems that three presentations can be enough for maintaining an image in memory during 10 years. Although a preservation in memory at an implicit level was already known since a few years, this new study shows that these tracks in memory can influence in a direct way the choice of the going participants, to certain cases, to produce a strong feeling of familiarity.

Why and how ?

The researchers try now to understand how such a memorization is possible from a biological point of view. The researchers suggest that this reports can be subtightened by a small group of hyperzpecialized neurons rather than a wide network of distributed neurons.
