Denna forskning stöds av en Young Investigator Award från det amerikanska National Alliance för forskning om schizofreni och depression samt en CPRF Award från den kanadensiska Psychiatric Research Foundation (till FD). ED fick stöd av en Wyeth-CIHR Post-doc. Författarna vill tacka Peter Seres för hjälp med fMRI datainsamling och Kristina Suen för hjälp med dataanalys.

Den experimentella designen införde här tillåter undersökning av de neurala korrelat för att minnas känslomässigt självbiografiska minnen. Denna konstruktion har potential att förbättra vår kunskap om hur hjärnan skapar affektiva fel (positiv eller negativ) att komma ihåg personliga minnen, och hur dessa fördomar kan anpassas med hämtning fokus (på känslomässiga eller icke-emotionella aspekter). Detta protokoll har ytterligare fördelar genom att den kan också användas med kliniska populationer (t ex...

brain imaging investigation of the neural correlates of emotional autobiographical recollection

Erinring av känslomässig självbiografiska minnen (AMS) är det viktigt att friska kognitiva och affektiva fungerande 1 - minnas positiva AMS är associerad med ökad personligt välbefinnande och självkänsla 2 får medan minnas och idisslande på negativa äf leda till affektiva störningar 3. Även om betydande framsteg har gjorts för att förstå hjärnans mekanismer bakom AM hämtning i allmänhet (över 4, 5), är mindre känt om effekten av känslor på den subjektiva ny upplevelse av AMS och tillhörande neurala korrelat. Detta beror delvis på det faktum att till skillnad från undersökningar av känslor påverkan på minne för laboratorie-baserade mikro händelser (Senaste i 6, 7-9), ofta gånger AM studier inte har ett tydligt fokus på de känslomässiga aspekterna av minnas personliga händelser (men se 10). Här presenterar vi ett protokoll som gör undersökning av de neurala korrelat till minnes emotionella äf med funktionell magnetkamera (fMRI). Ledtrådar för dessa minnen samlas innan du börjar skanna med hjälp av en självbiografisk minne frågeformulär (AMQ), därför gör för korrekt val av emotionella äf baserat på deras fenomenologiska egenskaper (dvs intensitet, livlighet, personlig betydelse). Detta protokoll kan användas på friska och kliniska populationer lika.
