Numerosi articoli dimostrano che il sonno ha effetti benefici sul consolidamento mnestico. In questo studio sono stati indagati questi effetti e studiati quali ritmi cerebrali tipici del sonno NREM possano favorire il rafforzamento della traccia mnestica. Nel gruppo sperimentale è stato analizzato l’esito di un riposino pomeridiano sull’apprendimento di immagini, confrontandolo con il gruppo di controllo che passava lo stesso periodo di tempo in veglia. I soggetti delle due condizioni sono stati testati immediatamente dopo l’apprendimento, dopo due ore, in cui un gruppo ha dormito e l’altro è rimasto sveglio, infine dopo quarantotto ore. Innanzitutto è stata cercata conferma che il sonno prevenisse il decadimento delle informazioni appena acquisite, successivamente è stata ricercata la correlazione tra attività ad onde lente e consolidamento.

Abstract
Numerous articles show that sleep has beneficial effects on memory consolidation. In this study these effects were investigated and it was studied if typical NREM sleep rhythms can favor the strengthening of the memory trace. In the experimental group, the effects of an afternoon nap on image learning were analyzed; it has been compared with the control group that spent the same period of time awake. Subjects of the two conditions were tested immediately after encoding, after two hours and when forty-eight hours were passed. First of all, the confirmation that sleep prevented the decay of newly acquired information was searched, then it has been tested the correlation between slow wave activity and consolidation.File | Dimensione | Formato | |
