brain imaging investigation of the memory-enhancing effect of emotion

Eventos emocionales tienden a ser más recordado que los no-emocional 1,2 eventos. Uno de los objetivos de los neurocientíficos cognitivos y afectivos es comprender los mecanismos neurales que subyacen a este efecto de mejora de la emoción sobre la memoria. Un método que ha demostrado ser particularmente influyentes en la investigación del efecto de la memoria para mejorar el de la emoción es el paradigma de la llamada memoria posterior (SMP). Este método fue utilizado originalmente para investigar los correlatos neurales de la memoria emocional, no 3, y, más recientemente, nosotros y los demás también lo aplicó con éxito en los estudios de la memoria emocional (revisado en 4, 5-7). Aquí se describe un protocolo que permite la investigación de los correlatos neurales de la memoria para mejorar el efecto de la emoción con la leche desnatada en polvo, en relación con eventos relacionados con resonancia magnética funcional por imágenes (fMRI). Una característica importante de la SMP es que permite la separación de la actividad cerebral específica asociada con la memoria de más actividad general asociada con la percepción. Por otra parte, en el contexto de la investigación del impacto de los estímulos emocionales, SMP permite la identificación de regiones del cerebro cuya actividad es susceptible a la modulación emocional de ambos generales / de percepción y procesamiento de la memoria específica. Este protocolo se puede utilizar en sujetos sanos 08/15, así como en pacientes clínicos en los que hay alteraciones en los correlatos neurales de la percepción de las emociones y los prejuicios en el recuerdo de eventos emocionales, como los que sufren de depresión y de trastorno postraumático por estrés (PTSD ) 16, 17.
