Slow-wave sleep (SWS) is well-established to play an important role in the sleep-dependent consolidation of declarative memory. According to the "active system consolidation hypothesis" slow oscillations and sleep spindles drive the repeated reactivation on newly-encoded memories during SWS and thereby promote their integration into long-term memory storage sites (Zhang & Gruber, 2019). Closed-loop acoustic stimulation (CLAS) has previously been shown to promote slow oscillations and spindle activity during sleep and improve verbal associative memory (Esfahani et al., 2023). The aim of the present study was to deliver for the first time acoustic stimulations in an ecological environment through the wearable device Dreem Headband to determine whether it can enhace the retention of 40 mock-words and their italian translations in a group of 34 young adults.
Numerose evidenze empiriche hanno dimostrato il ruolo centrale del sonno ad onde lente nel consolidamento sonno-dipendente delle memorie dichiarative. Secondo l'ipotesi del consolidamento di sistema attivo durante il sonno le oscillazioni lente e gli spindles guiderebbero la ripetuta riattivazione delle nuove informazioni codificate promuovendone l'integrazione nei siti neocorticali di immagazzinamento a lungo termine (Zhang & Gruber, 2019). La Closed-loop acoustic stimulation (CLAS) rappresenta una tecnica promettente nella promozione delle oscillazioni lente e dell'attività degli spindles durante il sonno, nonchè nel miglioramento delle memorie associative verbali (Esfahani et al., 2023). Il presente studio si propone di applicare per la prima volta le stimolazioni acustiche in setting ecologico mediante il dispositivo portatile Dreem Headband per valutarne gli effetti sulla ritenzione di 40 coppie di pseudoparole e delle rispettive traduzioni italiane in un gruppo di 34 giovani adulti.

Abstract
Slow-wave sleep (SWS) is well-established to play an important role in the sleep-dependent consolidation of declarative memory. According to the "active system consolidation hypothesis" slow oscillations and sleep spindles drive the repeated reactivation on newly-encoded memories during SWS and thereby promote their integration into long-term memory storage sites (Zhang & Gruber, 2019). Closed-loop acoustic stimulation (CLAS) has previously been shown to promote slow oscillations and spindle activity during sleep and improve verbal associative memory (Esfahani et al., 2023). The aim of the present study was to deliver for the first time acoustic stimulations in an ecological environment through the wearable device Dreem Headband to determine whether it can enhace the retention of 40 mock-words and their italian translations in a group of 34 young adults.File | Dimensione | Formato | |
