What are the latest advancements and findings in brainwave entrainment?3 answersBrainwave entrainment (BWE) is a therapeutic approach that uses external stimuli to alter brainwave frequency and states. Studies have shown that BWE can have positive effects on cognitive functioning, stress and anxiety, pain relief, headaches, mood, behavior, and premenstrual syndrome (PMS). BWE has been found to be effective in improving overall functioning and well-being in individuals. Recent advancements in BWE research include the use of rhythmic stimuli to entrain brainwaves, such as periodic auditory and visual signals. Additionally, the integration of BWE with immersive virtual reality (VR) technology has shown promising results in enhancing cognitive task performance, learning time, navigational skills, decision-making abilities, and orientation. However, more controlled trials are needed to further explore different protocols and outcomes of BWE.
What is the current progress on the works of brain networks?5 answersProgress in the study of brain networks is being made towards developing a standardized taxonomy and reporting system. The Workgroup for HArmonized Taxonomy of NETworks (WHATNET) was formed in 2020 to provide recommendations and identify areas of debate in network neuroscience. Challenges in this field include network scale, variability, dynamics, and multi-modal information. Additionally, research is focused on brain models at the microscopic, mesoscale, and large-scale levels. Functional connectivity between brain regions is of high importance and can be studied using resting-state networks (RSNs). The characteristics of RSNs and their functional connectivity can be influenced by the model order selection in independent component analysis (ICA). Graph theory-based analysis is also being used to study brain network organization, with measures such as small-world topology, hubs, and modularity being explored. A new parameter based on Zagreb topological indices and independence degree has been introduced for brain network analysis.
What are the recent advances in in vitro blood brain barrier models?5 answersRecent advances in in vitro blood-brain barrier (BBB) models include the development of complex multi-cellular assays. These models have been combined with other relevant organoid systems, such as cortical brain and liver spheroid models, in closed microfluidic systems to investigate drug distribution and metabolization. The integration of these models has enabled the measurement of permeation at the BBB and assessment of metabolite distribution. Organ-on-a-chip (OoC) technology has also emerged as a new approach to better recapitulate the dynamic in vivo human brain microenvironment, including the neural vascular unit (NVU). BBB-on-a-chip models using OoC technology have made substantial progress in the past decade, with applications in personalized medicine and drug discovery for neurological diseases. Hydrogel-based BBB-on-a-chip models have been explored to improve the proficiency of these models, mimicking the three-dimensional microarchitecture of tissues. However, no in vitro model has fully mimicked the complexity of the in vivo BBB microvasculature, and further studies are needed to develop an ideal model.
