póster.listelement.badge Declarative memory consolidation dynamics: new time windows and its implications for clinical application(2020) Moyano, Malen D.; Bonilla, Matías; Blanco, Marcelo F.; Brusco, Luis Ignacio; Pedreira, María Eugenia; Kaczer, Laura; Forcato, Cecilia"After encoding, memories go through a labile state followed by a stabilization process known as consolidation. Once consolidated they can enter a new labile state after the presentation of a reminder (cue) of the original memory, followed by a period of re-stabilization (reconsolidation). In both processes, once stabilization/re-stabilization is accomplished the memory cannot be modified. Currently there are studies that show a rapid stabilization after 30 min, while others studies show that stabilization occurs after 6h. However, there are no studies evaluating short and long delays simultaneously. Knowing that there are spontaneous waves of destabilization (without the re-exposure to keys linked to learning) on which the consolidation and memory persistence depend, here we investigate whether declarative memories in humans suffer spontaneous labilization/stabilization processes after learning or if they only pass through a single time window of lability."póster.listelement.badge Non-linear susceptibility to interferences in declarative memory formation(2021) Moyano, Malen D.; Carbonari, Giulia; Bonilla, Matías; Brusco, Luis Ignacio; Pedreira, María Eugenia; Kaczer, Laura; Forcato, Cecilia"After encoding, memories are in a labile state followed by a stabilization process known as consolidation.

This process is particularly favored by sleep, where the new information is spontaneously reactivated in the hippocampus, transferred and redistributed in neocortical networks facilitating long term consolidation. Also, during sleep, specifically during REM sleep, new memories are integrated into the stored information. From a neuroscientific perspective, dream content is proposed to be a consequence of the memory processes that occur during sleep. Thus, the incorporation of elements about the learned tasks during wakefulness in the content of a dream, can predict the performance of the task after sleep. Here, we developed a new paradigm to study whether dream content related to a new word learning task correlates with consolidation of new words and integration into the pre-existed semantic networks."póster.listelement.badge Word learning and semantic integration: memory reactivation as a key mechanism for building the mental lexicon(2020) Laurino, Julieta; Forcato, Cecilia; Pedreira, María Eugenia; Kaczer, Laura"Analyze the contribution of memory reactivation to the enhancement and updating of words’ meaning. Our hypothesis is that reactivating a novel word´s meaning could be a key mechanism for its lexical integration and plasticity."
