Memory is the persisting consequence of cognitive activities instigated by and engrossed on exterior information from the environment and commenced by an intensive on internal mental representations. Establishing a gut-brain axis (GBA) in health and disease has recently brought the gut, the main portal of communication with the external environment, to the forefront of this interaction. Dietary stimuli have long been linked to brain development, behavioral responses, and memory reflections. Vagus nerve, immune system, bacterial metabolites and products are just a few of the linkages that make up the GBA, a bidirectional arrangement of signaling pathways that connects the neurological system with the gastrointestinal tract. GBA involves two-way communication between central and enteric neural systems, connecting the brain's affective and cognitive regions to peripheral activities of the intestine. Recent scientific progress has highlighted the significance of gut microbiota in affecting these relationships. By controlling myelination at the prefrontal cortex, a crucial area for multifaceted cognitive behavior forecast and decision-making, this axis influences social behavior, including memory reflections. Humans may experience late myelination of the prefrontal cortex's axonal projections into the third decade of life, making it vulnerable to outside factors like microbial metabolites. It has been demonstrated that changes in the gut microbiome can change the microbial metabolome's composition, impacting highly permeable bioactive chemicals like p-cresol that may hinder oligodendrocyte differentiation. This review will discuss the memory reflections of the microbiota-gut and oligodendrocyte axis. Adopting this concept should encourage a new arena of thinking that recognizes the intricate central and periphery dynamics influencing behavior and uses that knowledge to develop novel therapies and interventions for maladjusted memory and learning systems.

Poly(lactic acid) (PLA) exhibits excellent shape memory properties but suffers from brittleness and a high glass transition temperature (T), limiting its utility in flexible and durable applications. This study explored the modification of PLA properties through the incorporation of poly(ethylene glycol) (PEG), varying in both content (5-20 wt%) and molecular weight (4000-12,000 g/mol), to enhance its suitability for specific applications, such as medical splints. The PLA/PEG blend, containing 15 wt% PEG and with a molecular weight of 12,000 g/mol, exhibited superior shape fixity (99.

Background: People with psychosis often experience a fragmented sense of self, making it difficult to integrate perceptions, memories, thoughts, and emotions related to themselves and others. Enhancing mentalization processes and fostering reflection are crucial for comprehensive recovery. As these processes are naturally developed through meaningful interactions and dialogue, incorporating a dialogic approach into the treatment of psychotic disorders may significantly support recovery.

The Effect of High-Intensity Interval Training (HIIT) on Brain-Derived Neurotrophic Factor Levels (BNDF): A Systematic Review.

Brain Sci

December 2024

Sport and Human Movement Science Research Group (SaHMS), Department of Sport Science, Nord University, 7600 Levanger, Norway.

Background/objectives: High-intensity interval training (HIIT) alternates short periods of intense exercise with recovery, effectively enhancing cardiorespiratory fitness, endurance, and strength in various populations. Concurrently, brain-derived neurotrophic factor (BDNF) supports neuronal resilience and activity-dependent plasticity, which are vital for learning and memory. This study aims to systematically review changes in BDNF levels in response to HIIT, with three primary objectives: evaluating the benefits of HIIT for BDNF modulation, assessing methodological quality and the risk of bias in reviewed studies, and identifying patterns in BDNF response based on HIIT protocols and population characteristics.

Elusive Gains of Cognitive Training: Limited Effects on Neural Activity Across Sessions.

Brain Sci

December 2024

Department of Psychology, Faculty of Humanities and Social Sciences, University of Zagreb, 10000 Zagreb, Croatia.

Background/objectives: Cognitive training paradigms rely on the idea that consistent practice can drive neural plasticity, improving not only connectivity within critical brain networks, but also ultimately result in overall enhancement of trained cognitive functions, irrespective of the specific task. Here we opted to investigate the temporal dynamics of neural activity and cognitive performance during a structured cognitive training program.

Methods: A group of 20 middle-aged participants completed 20 training sessions over 10 weeks.

Background: Spatial working memory is crucial for processing visual and spatial information, serving as a foundation for complex cognitive tasks. However, the effects of prolonged sleep deprivation on its dynamics and underlying neural mechanisms remain unclear. This study aims to investigate the specific trends and neural mechanisms underlying spatial working memory alterations during 36 h of acute sleep deprivation.
