The brain ages, but does it truly lose its ability to regenerate? Stem cells may reshape how we understand time. The human brain, with its remarkable architecture of billions of interconnected neurons, was long considered to be fixed once maturity was reached. For decades, scientists believed that, unlike other tissues in the body, the brain…
What if the true architects of brain adaptation were not neurons alone? For a long time, we believed that neurons alone were responsible for shaping our thoughts, memories, and adaptive capabilities. This perspective, firmly rooted in classic neuroscience research, led to the significant undervaluation of glial cells, particularly astrocytes. For decades, these cells were merely…
For a long time, frontotemporal degeneration can stay subtle and be mistaken for stress, fatigue, or a “personality change.” Spotting early signs helps people act sooner and tailor support. It is fascinating to consider that, just as a great civilization may crumble not due to an external disaster but because of internal flaws, the human…
Sleep doesn’t just store memories, it helps “digest” them. When it’s missing, traumatic images return sharper and the mind stays on edge. Sleep, the nightly journey we undertake without a second thought, is more than just a refuge for a tired body. It functions like a silent architect, building, classifying, and sometimes demolishing our memories….
Six weeks of running in grandfather mice, and the grand-offspring learn better. This unexpected carryover points to epigenetics, possibly involving microRNAs. The influence of physical exercise on our well-being is a widely studied topic in the health sciences. There is compelling evidence that regular activity enhances physical fitness, mental health, and even longevity. However, an…
In depression, treatments often remain partial. Brain stimulation technologies offer a new approach, still under clinical evaluation. Depression is a complex psychiatric disorder that affects a significant portion of the global population. It manifests as a disturbance in mood, profoundly influencing affective and cognitive processes, as well as the capacity to manage everyday tasks. Owing…
