Long considered permanently inactive, the X chromosome may “wake up” with age in certain brain cells. A finding that opens new avenues for understanding cognitive decline. For decades, brain aging has been investigated mainly through hormonal, metabolic and inflammatory lenses. A recent discovery suggests that part of the answer may lie deeper, within the genome’s…
Addiction is often framed as a behavioral or cognitive disorder.Yet it also reflects a deeper disruption of bodily regulation, affecting the interplay between sensation, emotion, and control. Addiction is often described as a loss of control, a slow erosion of the individual’s capacity to choose. However, long before the mind recognizes what is happening, the…
In the 19th century, opium was more than a commodity, it was a weapon.By embedding addiction within an empire, it turned a global power into a vulnerable society, exposing the links between dependency and domination. The story of opium does not begin in the smoky dens of Canton but far earlier, in the fertile valleys…
What if thinking alone could help the body move again? By translating intention into action, BCIs reactivate dormant neural circuits. Every year, more than sixteen million people around the world experience a stroke. For almost one third of them, the consequences are lasting: paralysis, language impairments, memory difficulties, or depression. Although traditional rehabilitation such as…
The language of the body comes before words. In early childhood, gestures, rhythms, and touch create a lasting emotional memory that structures the social brain. Attachment begins long before speech emerges. It is woven through daily bodily exchanges, a shared gaze, a hand resting on the skin, a breathing rhythm that slowly synchronizes over the…
Between forgetting and transformation, memory does more than preserve the past, it reshapes it. Forgetting a painful memory on purpose has been a dream as old as memory itself. Since antiquity, humanity has sought in forgetfulness a way to ease its inner wounds. In Greek mythology, the souls descending into the Underworld would drink the…
Sleep may not depend on neurons alone. Recent studies suggest that other, long-overlooked cells may help regulate its mechanisms. Long regarded as mere support cells, astrocytes are now emerging as key players in the orchestration of sleep. Recent studies reveal that these glial cells do far more than accompany neurons they actively regulate sleep cycles,…
Is altruism learned, or is it innate? Neuroscience suggests that even before language, children display spontaneous helping behaviors. Born from the need to live together, the human brain thinks, feels, and acts in constant relation with others. Shaped by social life, it deciphers intentions, shares emotions, and continuously adjusts its behavior to those around it….
Cognitive giftedness fuels many, often conflicting representations. Current research seeks to offer a more rigorous understanding. For a long time marginalized or dismissed as mere cliché, over-efficiency—whether manifesting as high intellectual potential (HIP) or very high intellectual potential (VHIP)—is now receiving renewed scientific attention. Recent research in cognitive neuroscience, neuro-psychoanalysis and clinical psychology converge to…
Games are increasingly used in schools as a learning tool. But beyond their appeal, what does research really say about their cognitive effects? Classrooms turned into interactive quests, students collecting badges like video game players, teachers becoming storytellers of a gamified learning journey—education is undergoing a remarkable transformation.At the heart of this shift lies a…
