póster.listelement.badge Formación de memorias episódicas aversivas durante la pandemia por COVID-19(2021) León, Candela S.; Bonilla, Matías; Urreta Benítez, Facundo A.; Brusco, Luis Ignacio; Wang, Jingyi; Forcato, Cecilia"La memoria episódica es la capacidad de recordar qué, dónde y cuándo ocurrió un evento. Además, existe consenso en cuanto a que los eventos agradables o aversivos se recuerdan mejor que los eventos neutrales y que los procesos de memoria episódica están modulados por la ansiedad y la depresión. La salud mental de las personas se ha deteriorado debido a la pandemia de COVID-19, mostrando un aumento de los síntomas de ansiedad y depresión. Aquí, planteamos la hipótesis de que el aumento de síntomas negativos modifica la capacidad de codificar y consolidar recuerdos. Para estudiar esto, evaluamos los efectos del contexto emocional en la codificación y consolidación de recuerdos episódicos neutrales y aversivos."artículo de publicación periódica.listelement.badge Impairment of aversive episodic memories during Covid-19 pandemic: The impact of emotional context on memory processes(2022-06) León, Candela S.; Bonilla, Matías; Urreta Benítez, Facundo A.; Brusco, Luis Ignacio; Wang, Jingyi; Forcato, Cecilia"The threatening context of the COVID-19 pandemic provided a unique setting to study the effects of negative psychological symptoms on memory processes. Episodic memory is an essential function of the human being related to the ability to store and remember experiences and anticipate possible events in the future. Studying this function in this context is crucial to understand what effects the pandemic will have on the formation of episodic memories. To study this, the formation of episodic memories was evaluated by free recall, recognition, and episode order tasks for an aversive and neutral content. The results indicated that aversive episodic memory is impaired both in the free recall task and in the recognition task. Even the beneficial effect that emotional memory usually has for the episodic order was undermined as there were no differences between the neutral and aversive condition. The present work adds to the evidence that indicates that the level of activation does not modify memory processes in a linear way, which also depends on the type of recall and the characteristics of the content to be encoded."póster.listelement.badge Impairment of aversive episodic memories during covid-19 pandemic: The impact of emotional context on memory processes(2021) León, Candela S.; Bonilla, Matías; Urreta Benítez, Facundo A.; Brusco, Luis Ignacio; Wang, Jingyi; Forcato, Cecilia"Episodic memory is the ability to recall about what, where and when the event happened. Furthermore, there is a consensus that pleasant or aversive events are better remembered than neutral events and that episodic memory processes are modulated by anxiety and depression. People's mental health has deteriorated due to the COVID-19 pandemic, showing a growth in anxiety and depressive symptoms. Here, we hypothesize that the increase in negative symptoms modifies the ability to encode and consolidate memories. To study this, we evaluated the effects of emotional context on encoding and consolidation of aversive and neutral episodic memories."artículo de publicación periódica.listelement.badge Positive and neutral updating reconsolidate aversive episodic memories via different routes(2021-01) Wang, Jingyi; Chen, Boxuan; Sha, Manqi; Gu, Yiran; Wu, Haitao; Forcato, Cecilia; Qin, Shaozheng"Aversive memories are long-lasting and prone to have adverse effects on our emotional wellbeing and mental health. Yet, how to remedy the maladaptive effects of aversive memories remains elusive. Using memory reactivation and emotional updating manipulations, we investigated how positive and neutral emotion updates aversive memories for reconsolidation in humans. We found that positive updating after reactivation was equivalent to neutral updating in altering true memories of the aversive story, but introduced more false memory. Moreover, an additional 12 hours of sleep reconsolidation did not further enlarge true memory differences, but attenuated the effect of reactivation and updating on false memory. Interestingly, the neutral rather than the positive updating reduced the emotional arousal of the aversive memory 24 hours later. Our findings provide novel insights into real-world therapeutic applications regarding how updating with positive and neutral emotion may reshape aversive memories, especially when taking wake- and sleep-filled reconsolidation into account."póster.listelement.badge The role of sleep in episodic memory reconsolidation: project and preliminary results(2021) Moyano, Malen D.; Tassone, Leonela M.; Brusco, Luis Ignacio; Wang, Jingyi; Forcato, Cecilia“Episodic memory is a subtype of declarative memory, defined as the ability to remember how, where and when past events occurred. Consolidated memories can be reactivated by a reminder of the original memory and can enter a new labile state, followed by a period of re-stabilization (reconsolidation). Sleep facilitates the consolidation of newly encoded memories and enhances the memory persistence 6 months after learning. It was demonstrated that a short nap accelerated memory re-stabilization of a list of nonsense syllable pairs, and facilitated the reconsolidation of the reactivated object-location memory, at short-term. Here, we aim to study the role of sleep on memory persistence of a neutral episodic memory through the reconsolidation process.”
