The impact of sleep hygiene on emotional variables and memory processes in prision inmates
(2021) Martín, Alejandra; Bonilla, Matías; Tassone, Leonela M.; Gallo, Francisco; Forcato, Cecilia
"Having a good sleep quality is essential for a healthy life. Lack or poor quality of sleep can negatively affect various brain functions such as emotional processing and memory acquisition and consolidation. In addition, prolonged sleep deprivation, as well as the deterioration of the sleep quality are correlated with depressed mood, anger, aggressive behavior and anxiety. The prison experience can be inherently stressful and lead to disturbed sleep patterns. In prison, the most common sleep disorder is insomnia. When left untreated, it can negatively affect daytime functioning and work productivity, and it can influence inmate adverse behavior such as exacerbating irritability or aggression. Improving sleep in prison offers the potential to positively impact several of these common risk factors for both staff and inmates. Thus, we propose a sleep hygiene treatment to improve sleep habits in the prison environment. Here, we will discuss the project and preliminary data of one-month treatment of sleep hygiene in prison inmates."
Memory reconsolidation as a tool to endure encoding deficits in elderly
(2020-08) Tassone, Leonela M.; Urreta Benítez, Facundo A.; Rochon, Delfina; Martínez, Paula B.; Bonilla, Matías; León, Candela S.; Muchnik, Carolina; Solis, Patricia; Medel, Nancy; Kochen, Silvia; Brusco, Luis Ignacio; Moyano, Malen D.; Forcato, Cecilia
"Normal aging involves changes in the ability to acquire, consolidate and recall new information. It has been recently proposed that the reconsolidation process is also affected in older adults. Reconsolidation is triggered after reminder presentation, allowing memories to be modified: they can be impaired, strengthened or changed in their content. In young adults it was previously shown that the presentation of repetitive reminders induces memory strengthening one day after reactivation and the presentation of at least one reminder increases memory persistence several days after reactivation. However, until now this process has remained elusive in older adults. We hypothesize that older adults need a stronger reminder to induce memory strengthening through the reconsolidation process than young adults. To test this, we perform a three-day experiment. On day 1, participants learned 15 sound-word associations, on day 2 they received no reminders (NR group), one reminder (R group) or two rounds of reactivations (Rx2 group). Finally, they were tested on day 7. We found that, contrary to our hypothesis, older adults show a memory improvement triggered by repeated labilization/reconsolidation processes to an equal extent than young adults. These results open new perspectives into the use of reconsolidation to improve daily acquired information and the development of therapeutic home used tools to produce memory enhancement in healthy older adults or those with cognitive decline."
Odor cueing during sleep improves consolidation of a history lesson in a school setting
(2022-03-22) Vidal, Vanesa; Barbuzza, Alejo R.; Tassone, Leonela M.; Brusco, Luis Ignacio; Ballarini, Fabricio; Forcato, Cecilia
"Sleep is a key factor in memory consolidation. During sleep, information is reactivated, transferred, and redistributed to neocortical areas, thus favoring memory consolidation and integration. Although these reactivations occur spontaneously, they can also be induced using external cues, such as sound or odor cues, linked to the acquired information. Hence, targeted memory reactivation during sleep represents an advantageous tool for improving memory consolidation in real-life settings. In this study, our goal was to improve the consolidation of complex information such as that of a history lesson, using a school study session in the presence of an odor, and a reactivation round while sleeping at home on the same night of the acquisition, without using additional study sessions. We found that complex information can be associated with an odor in the classroom and that one session of reactivation during the frst night of sleep in the students’ houses improves its consolidation. These results bring new evidence for the implementation of reactivation during sleep in real-life settings."
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.”
Sleep hygiene impacts on episodic memories in young and older adults during quarantine by Covid-19: preliminary results
(2020) Tassone, Leonela M.; Martínez, Paula B.; Moyano, Malen D.; Solferino, Cecilia; Feldberg, Carolina; Tartaglini, Florencia; Brusco, Luis Ignacio; Forcato, Cecilia
"Sleep benefits off-line consolidation of recent acquired information. Insufficient sleep impairs health, especially key components of cognition, resulting in poorer attention and impaired long-term memory. Currently, due to quarantine by Covid-19, sleep routines and sleep quality were modified and affected throughout the population. Preliminary results from our lab showed that episodic memory formation was impaired by emotional variables, such as anxiety and depression . Furthermore, sleep hygiene is fundamental to improve sleep habits. Sleep hygiene refers to a set of practices and environmental factors that are related to good sleep quality. Here, we perform a sleep hygiene treatment to study its impact on episodic memories and on emotional variables such as anxiety and depression in young and older adults during quarantine by Covid-19."
