póster.listelement.badge K-Complex detection algorithm in non-REM sleep(2020) Vázquez Chenlo, Aylin; Carosi, Julia; Carbonari, Giulia; Forcato, Cecilia; Ramele, Rodrigo"In order to evaluate the relation between KC and memory processes our main goal was to create a method with Machine Learning techniques to characterize and identify KCs."póster.listelement.badge K-complex localization and classification algorithm(2021) Vázquez Chenlo, Aylin; Carbonari, Giulia; Carosi, Julia; Forcato, Cecilia; Ramele, Rodrigo"K-Complexes (KCs) are events present in non-rapid eye movement (non-REM) sleep, which have cellular dynamics similar to slow waves and have 3 distinguishing components: an initial P200, a posterior N500 and a final P900. Sleep plays a fundamental role in memory consolidation, favoring the transfer of new information from the hippocampus to the neocortex and its cortico-cortical redistribution. There are currently no studies that directly link KCs with memory processes, so they are not being considered as a possible facilitating event of this hippocampal-cortical dialogue. "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. 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 depends, here we investigate whether declarative memories in humans go through spontaneous abilization/stabilization processes after learning or if they only pass through a single time window of lability."artículo de publicación periódica.listelement.badge Non-linear susceptibility to interferences in declarative memory formation(2022-06-29) Moyano, Malen D.; Carbonari, Giulia; Bonilla, Matías; Pedreira, María Eugenia; Brusco, Luis Ignacio; 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 of the original memory, followed by a period of re-stabilization (reconsolidation). During these periods of lability the memory traces can be modified. Currently, some studies show a rapid stabilization after 30 min, while others show that stabilization occurs after longer periods (e.g. > 6 h). Here we investigate the effect of an interference treatment on declarative memory consolidation, comparing distinct time intervals after acquisition. On day 1, participants learned a list of non- syllable pairs (List 1). 5 min, 30 min, 3 h or 8 h later, they received an interference list (List 2) that acted as an amnesic agent. On day 2 (48 h after training) participants had to recall List 1 first, followed by List 2. We found that the List 1 memory was susceptible to interference when List 2 was administered 5 min or 3 h after learning but not when it was administered 30 min or 8 h after. We propose the possibility that this rapid memory protection could be induced by a fast and transient neocortical integration. Our results open a discussion about the contribution of molecular and systemic aspects to memory consolidation."póster.listelement.badge Slow wave detection algorithm in non-REM sleep(2020) Carbonari, Giulia; Carosi, Julia; Vázquez Chenlo, Aylin; Moris, Eugenia; Forcato, Cecilia; Ramele, Rodrigo; Larrabide, Ignacio"Online detection of slow waves."
