Evidencias recientes apuntan a las emociones y el sueño fisiológico como dos factores moduladores de la memoria declarativa, especialmente cuando se trata de recuperar información contextual relacionada con un evento del pasado. Sin embargo, permanece sin desvelar si la carga emocional que acompaña a un evento es en sí misma suficiente, o si, al igual que los eventos desprovistos de carga afectiva, necesitan del periodo de sueño subsiguiente para su estabilización y consolidación en las redes neuronales que subyacen a este tipo de memoria.<br/>El presente estudio evalúa el efecto de la privación de sueño sobre la memoria para estímulos con y sin carga emocional, utilizando el paradigma saber/recordar. La privación de sueño disminuyó selectivamente el recuerdo de las imágenes neutras y con bajo arousal emocional, sin alterar la recuperación de imágenes negativas o con alto arousal emocional. Dado que el sueño parece proteger de posibles interferencias la memoria declarativa, es posible que el grado de diferenciación que adquieren las imágenes negativas durante la codificación sea suficiente para que queden protegidas de interferencias posteriores. Desde esta perspectiva teórica, sueño y emociones parecen incidir de forma crítica en el recuerdo de eventos pasados, de forma que uno lo haría fundamentalmente a través del hipocampo (sueño) y el otro a través de la amígdala (emociones). |

Recent evidence points to emotions and physiological sleep as two modulatory factors of declarative memory, especially when it comes to retrieving contextual information related to a past event. However, it remains undisclosed if the emotional load that accompanies an event is itself sufficient, or if, like events devoid of affective load, they need the subsequent sleep period for their stabilization and consolidation in the neural networks that Underlie this type of memory.<br/>The present study evaluates the effect of sleep deprivation on memory for stimuli with and without emotional load, using the know / remember paradigm. Sleep deprivation selectively decreased the memory of neutral images and with low emotional arousal, without altering the recovery of negative images or with high emotional arousal. Since the dream seems to protect declarative memory from possible interference, it is possible that the degree of differentiation acquired by negative images during encoding is sufficient to protect them from subsequent interference. From this theoretical perspective, sleep and emotions seem to critically influence the memory of past events, so that one would do so fundamentally through the hippocampus (dream) and the other through the amygdala (emotions). |
