dc.description.abstract: "Sleep paralysis is a period of transitory immobility which occurs during sleep onset or offset. It is characterized by the inability to perform voluntary movements when the person feels awake and conscious about the environment. During an episode of sleep paralysis can occur different types of hallucinations: The Intruder, characterized by the sense of an evil and threatening presence, visual and tactile hallucinations. The Incubus, characterized pressure on the chest and other body parts, breathing difficulties, feelings of suffocation, choking, pain and morbid thoughts of imminent death. Unusual body experiences which includes Illusory Movement Experiences (IMEs) and Out of Body Experiences (OBEs). IMEs are vestibular sensations such as the sensation of rolling or floating, and/or motor sensations of displacement without a visual component.The OBEs are an altered state of consciousness, defined as the experience in which an observer perceives the world from a point of view outside of their physical body. Unlike the other two components (incubus and intruder), during IMEs and OBEs the person may not feel body paralysis, and they are considered as more pleasant. OBEs during sleep paralysis can occur spontaneously or it can be induced with training by the recognition of an aura that precedes the experience. Here, we will discuss preliminary results of an online survey with subjects who had unusual sleep experiences, such as OBEs and Sleep Paralysis and its clinical implications."

dc.description.abstract: "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."

dc.description.abstract: "During sleep, humans experience offline visual content that we call dreams, which are typically emotional and lack rational judgment about their strangeness. However, during lucid dreaming (LD), subjects know they are dreaming and can control the dream content. Another type of awere dream experience is the out-of-body experience (OBE) initiated from sleep paralysis. Although the differences between non-LD, LD and OBEs are evident, there is no record in the literature of such differences in dream content and some researchers describe OBEs as a type of LD. We conducted interviews with subjects who experienced LD and subjects who had OBEs frequently. A portion of them kept a dream journal for two months with precise instructions on how to write down their dreams. The collected dreams were analyzed by automatic methods of analysis of emotions such as EmoLex and Sentisense, also with classifiers such as Empath. The dream stories provided by the participants were scored with a series of ratings using a method based on Hall and Van de Castle's dream content scoring system upon which we developed variations and additional measures to adapt to the requirements of our task. The scoring was divided into sections, hought/emotion/action, presence of entities/characters and social interactions, sensory descriptions, spatial references, fantasy content, among others. Here we present the preliminary progress of this study of oneiric content."

dc.contributor.author: León, Candela S.; Bonilla, Matías; Urreta Benítez, Facundo A.; Forcato, Cecilia
dc.description.abstract: "Episodic memory is the ability to recover past experiences and projects ourselves into the future. It is related to contextual information (both spatially and temporally). This type of memory is highly sensitive to aging, the passage of time, forgetfulness, interference and confusion. Furthermore, episodic memory processes are modulated by both anxiety and depression. People's mental health has deteriorated due to the Covid-19 pandemic, showing higher levels in both values. There is a general consensus that pleasant or aversive events are better remembered than neutral events. Regarding false memories, there is no such consensus. Some authors found that emotional content generates more false memories, however, it was also found that negative content reduces false memories. In this study we evaluated the effects of emotional variables, such as anxiety and depression, on memory encoding and consolidation of true and
false details of aversive and neutral stories."

dc.description.abstract: "False memories are memories of events that did not happen or are altered in their content. It has been shown that not only small distortions can be introduced into old memories but also entire memories of events that never occurred can be implanted. Age is a crucial factor in the formation of false memories. Currently there is no consensus on which age range is more vulnerable. Since the COVID-19 pandemic, anxiety and depression values are increased and these factors also influence the formation of false memories.Thus, our aim was to study how age and mood factors, such as anxiety and depression, influence the formation of false memories."

dc.description.abstract: "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."

dc.description.abstract: "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."

dc.contributor.author: Vázquez Chenlo, Aylin; Carbonari, Giulia; Carosi, Julia; Forcato, Cecilia; Ramele, Rodrigo
dc.description.abstract: "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. "
