Dit onderzoek werd ondersteund door een Young Investigator Award van de Amerikaanse Nationale Alliantie voor onderzoek naar schizofrenie en depressie en een CPRF Award van de Canadese Psychiatric Research Foundation (FD). ED werd ondersteund door een Wyeth-CIHR post-doctorale beurs. De auteurs willen Peter Seres bedanken voor de hulp bij het fMRI verzamelen van gegevens en Kristina Suen voor hulp bij data-analyse.

Het experimentele ontwerp hier geïntroduceerd kan onderzoek naar de neurale correlaten van herinneren emotionele autobiografische herinneringen. Dit ontwerp heeft het potentieel om onze kennis van hoe het brein genereert affectieve fouten (positief of negatief) in het herinneren van persoonlijke herinneringen van tevoren, en hoe deze vooroordelen kan gemoduleerd worden door het ophalen van focus (op emotioneel of niet-emotionele aspecten). Dit protocol heeft extra voordelen in dat het ook gebruikt kan worden met klinis...

brain imaging investigation of the neural correlates of emotional autobiographical recollection

Herinnering aan emotionele autobiografische herinneringen (AMS) is belangrijk voor een gezonde cognitieve en affectieve functioneren 1 - herinneren positieve AMS is geassocieerd met een verhoogde persoonlijk welzijn en gevoel van eigenwaarde 2, kan terwijl herinneren en herkauwen van negatieve amendementen leiden tot affectieve stoornissen 3. Hoewel er aanzienlijke vooruitgang is geboekt in het begrijpen van de hersenen onderliggende mechanismen van AM ophalen in het algemeen (beoordeeld in 4, 5), minder bekend over het effect van emotie op de subjectieve re-ervaring van AMS en de bijbehorende neurale correlaten. Dit is gedeeltelijk te wijten aan het feit dat, in tegenstelling tot het onderzoek van de emotie effect op het geheugen voor laboratorium-op basis van micro-evenementen (beoordeeld in 6, 7-9), vaak tijden AM studies niet een duidelijke focus op de emotionele aspecten hebben van onthouden van persoonlijke gebeurtenissen (maar zie 10). Hier presenteren we een protocol dat het onderzoek naar de neurale correlaten van herinneren emotionele amendementen met behulp van functionele magnetische resonantie imaging (fMRI) mogelijk maakt. Aanwijzingen voor deze herinneringen zijn vóór het scannen verzameld door middel van een autobiografisch geheugen vragenlijst (AMQ), waardoor deze voor de juiste keuze van emotionele amendementen op basis van hun fenomenologische eigenschappen (dat wil zeggen, intensiteit, levendigheid, persoonlijke betekenis). Dit protocol kan gebruikt worden in een gezonde en klinische populaties gelijk.
