Apprendimento della sicurezza sociale nel sistema cerebrale dell'ossitocina

10 giugno 2026 aggiornato da: Angela Fang, University of Washington
I ricercatori stanno conducendo questo studio di ricerca per esaminare se l'ossitocina migliora l'apprendimento della sicurezza sociale (apprendimento sicuro attraverso l'esperienza di un altro individuo) nelle persone con disturbo d'ansia sociale (SAD) rispetto ai volontari sani. L'ossitocina è un ormone che può anche fungere da messaggero chimico nel cervello. L'ossitocina svolge un ruolo in una serie di funzioni, inclusa la risposta alla paura e alle interazioni sociali. In questo studio, i ricercatori vorrebbero confrontare gli effetti dell'ossitocina e degli spray nasali placebo negli adulti con SAD e negli adulti sani. Questo studio di ricerca confronterà uno spray nasale di ossitocina con uno spray nasale placebo. A questo studio di ricerca prenderanno parte circa 120 persone, tutte presso l'Università di Washington (UW).

Descrizione dettagliata

L'obiettivo del presente studio è esaminare il ruolo potenziale dell'ossitocina nel migliorare l'apprendimento sociale nel SAD. L'ipotesi principale dei ricercatori è che l'apprendimento vicario dell'estinzione contribuirà all'apprendimento sulla sicurezza e che l'ossitocina potenzierà l'apprendimento vicario dell'estinzione nei pazienti con SAD, rispetto ai controlli sani (HC). I ricercatori testeranno direttamente l'effetto dell'ossitocina intranasale e del placebo corrispondente sui meccanismi cerebrali alla base dell'apprendimento vicario dell'estinzione utilizzando un nuovo compito. 60 adulti con SAD e 60 partecipanti sani di controllo eseguiranno un compito che prevede tre fasi: (i) una procedura standard di acquisizione della paura sociale mentre si trova in un finto scanner, seguita da (ii) un'estinzione vicaria e (iii) procedura di test di reintegrazione della paura, durante la scansione durante la risonanza magnetica funzionale (fMRI). I partecipanti riceveranno ossitocina o placebo prima della fase di estinzione. Gli investigatori misureranno anche le risposte di conduttanza cutanea come indice di apprendimento in ciascuna fase.

Misura Descrizione
Lasso di tempo
Neural Responses in the CS+R vs CS+S Contrast in the Insula During the Extinction Phase
Lasso di tempo: immediately (45 minutes) after receiving drug
Change in task-related blood oxygen level dependent (BOLD) responses in the insula during vicarious extinction (specifically for CS+R (reinforced) versus CS+S (non-reinforced) conditions). Changes in BOLD responses refer to differences in neural responses between these two task conditions, which were extracted from the insula region of interest and estimated using a general linear model. Higher mean responses reflect greater discrimination (better able to distinguish between threat and safety cues) between the task conditions.
