Sitting for hours each day is no longer just a cardiovascular or metabolic health concern, it has become a serious warning sign for the brain. In a world where sitting has become the invisible norm, from the office chair to the driver’s seat, the couch to the screen, sedentary behavior is no longer a simple…
In recent years, the prospect of diagnosing mental disorders through brain imaging has gained significant momentum. With advances in neuroimaging and the rise of artificial intelligence, researchers are beginning to identify so‑called “biotypes”, distinct brain profiles thought to reflect mechanisms specific to depression, anxiety, and other psychiatric conditions. This transdiagnostic approach aspires to move beyond…
Can learning a foreign language still stimulate the aging brain? Once considered a marginal question in cognitive science, this issue is now taking center stage in the neuroscience of aging. As life expectancy continues to rise, preserving brain function has become a critical concern. Many strategies have been proposed to slow age-related cognitive decline, but…
What if running a marathon didn’t just drain your muscles, but also quietly reshaped the very structure of your brain? At the heart of this transformation lies a subtle but essential player: myelin. This sheath, which insulates nerve fibers, isn’t just responsible for the speed of neural signals, it may also act as an emergency…
For decades, neuroscience has maintained a clear distinction between two categories of brain disorders. On one side are neurodevelopmental disorders, which emerge early in life and reflect disruptions in brain maturation. On the other are neurodegenerative diseases, typically associated with aging and characterized by the progressive breakdown of specific neural structures. This division has long…
Every year, thousands of individuals lose the use of their limbs due to stroke, spinal cord injury, or neurodegenerative disease. When both speech and movement fall silent, communication becomes a matter of survival. This raises a central question: can brain activity be harnessed to restore a voice to those who have lost theirs? Brain-computer interfaces…
One evening, in the waiting room of a hospital, a ten-year-old girl clutched her mother’s hand with unusual insistence. She stared at her mother’s face, then quickly looked away, as if something no longer made sense.“Your head is tiny… and I think my arms are getting longer,” she whispered, caught between fear and amazement. Her…
We’ve all experienced it, leaving a room feeling inexplicably lighter, simply because the atmosphere was cheerful. Or conversely, entering a space where something felt off, an invisible tension lingering in the air, and suddenly feeling uneasy without knowing why. What others feel, in a strange and almost magical way, ends up affecting us. But why…
Mr. L., 56, lost his left leg in a motorcycle accident. Just days after the amputation, he began experiencing intense, localized pain in his left foot, a foot that no longer existed. He described it as a burning sensation, sometimes cramping, as though his toes were painfully curled. No topical treatment provided relief. When asked…
Professor M. lived surrounded by books, in a house lined with ancient volumes and dictionaries. Reading and teaching were his life, language was his home, as familiar to him as the walls he lived in. Until the day words began to slip away. One morning, while preparing a lecture, something gave way. The words hovered…
