The practical applications of this discovery are wide-ranging and profound.

Pedagogical and psychological implications These results therefore constitute a bridge between the experimental results in the animal model and the investigation of human memory.

Indeed, the subjects who could freely navigate through the virtual environment promoted a theta phase code that favored the fixation and retrieval of information, as was the case in previous studies carried out with rodents. Daniel Pacheco, the first author of the study. One of them corresponded to the encoding of the information the other, to the retrieval of previously stored information: the reactivation of memory,' explains Dr. But, in addition, what happened was that there were two consecutive phenomena, separated by milliseconds. 'In the subjects who had had the possibility to carry out active navigation, an increase in theta oscillations was identified that made learning and subsequent memory more efficient.

In this second modality, therefore, the subjects did not exercise any control over how to memorize the dispersed objects in the virtual environment.Д«y studying the electrophysiological activity of the hippocampus and testing the recognition of the objects at the end of the experiment, the researchers were able to verify the importance of active learning in each of the participants. Navigation could be active, whereby participants freely controlled their movements or passive, if it was another subject who planned the route and, therefore, who decided the order of exposure to the images. In a virtual reality game, participants navigated a square track, and were asked to recall images of objects presented at different locations on the track. The work-to be published in the prestigious scientific journal PNAS ( Proceedings of the National Academy of Sciences of the United States of America) in the week starting 1 March 2021-is based on an experiment carried out with epilepsy patients.

The key lies in the oscillations of theta waves generated by the hippocampus of the human brain, when it is the brain that has control of the learning process. Rodrigo Rocamora from Hospital del Mar, have identified for the first time in humans, the mechanism responsible for this phenomenon. Now, an international group of researchers led by ICREA Research Professor Paul Verschure from the SPECS laboratory at the Institute for Bioengineering of Catalonia (IBEC) and Professor Nikolai Axmacher from the Department of Neuropsychology at Ruhr-UniversitГ¤t Bochum (Germany), in collaboration with Pompeu Fabra University and Dr.
