Highly Demand Working Memory Intervention Weakens a Reactivated Threat Memory and the Associated Cognitive Biases.

Anxiety disorders are the most frequent type of mental disorder. Threat-conditioning memory plays a central role in anxiety disorders, impacting complex cognitive systems by modifying behavioral responses to fearful stimuli and inducing an overestimation of potential threats. Here, we analyzed the reminder-dependent amnesia on physiological responses, unconditioned stimulus (US) expectancy ratings, and measures of cognitive bias towards the threat of a threat-conditioning memory.

Remembering how to run: A descriptive wheel run analysis in CF1 male and female mice.

Physical exercise is known to have beneficial effects on general health and wellbeing in humans and it is also related to neuronal plasticity, increasing neurogenesis and consequently leading to improvements in processes such as learning and memory. In this sense, wheel running performance in mice appears as an extensively used behavioral approach for neurobiological studies. Here, we explored the running patterns in CF1 male and female mice allowing voluntary wheel running for 20 min along three consecutive days.

Improvement of episodic memory retention by a memory reactivation intervention across the lifespan: from younger adults to amnesic patients.

Spontaneous reactivation of recently acquired memories is a fundamental mechanism of memory stabilization. Re-exposure to specific learned cues during sleep or awake states, namely targeted memory reactivation, has been shown to improve memory retention at long delays. Manipulation of memory reactivation could have potential clinical value in populations with memory deficits or cognitive decline.

Psychological distress and mental health trajectories during the COVID-19 pandemic in Argentina: a longitudinal study.

Psychological-distress increased at the onset of the COVID-19 pandemic in Argentina. Longitudinal studies in developing countries are scarce. Particularly, Argentina had one of the longest lockdowns.

Psychometric validation of the survey of autobiographical memory: confirmatory factor analysis and network analysis.

Autobiographical memory (AM) represents the ability to remember personal experiences. There are several laboratory or neuropsychological tasks to assess different aspects of memory function. However, there has been little research on self-reported AM ability.

Effects of Threat Conditioning on the Negative Valanced Systems and Cognitive Systems.

Threat conditioning is held as a model of anxiety disorders. However, this approach is focused on implicit responses evaluated in a single day. Here, we evaluated negative-valence, positive-valence and cognitive-systems in order to evaluate the extent to which threat conditioning models anxiety disorders.
