For decades, researchers have sought to unravel the mechanisms of consciousness. But beyond neural data, one essential dimension continues to resist explanation: lived experience itself. In 1974, the American philosopher Thomas Nagel, a professor at New York University and a major figure in the philosophy of mind, published what would become a landmark paper entitled…
The brain never truly resets. Yet the idea of starting over can be enough to boost motivation and change how we see the future. Each new year acts as a signal. It invites reflection, projection, and a reconsideration of what once seemed firmly established. Biologically, however, nothing distinguishes the brain from one day to the…
Between brain plasticity and unconscious repetition, anxiety is embedded in reinforcing neural circuits. In a world saturated with information, social pressure, and simultaneous demands, anxiety no longer appears as a purely individual symptom. It reflects an era and a neural architecture constantly forced to adapt. Each brain, exposed to uninterrupted streams of stimulation, becomes the…
Long confined to the classroom, learning is now expanding outdoors. Research suggests that natural environments can improve attention and support the cognitive processes involved in learning. For a long time, schooling was conceived within four walls. Protective, structured, reassuring walls. Over the past decade, however, a quiet shift has been taking place in schoolyards, public…
The rise of artificial intelligence marks a turning point in how we relate to the world and to ourselves. Between the illusion of control and shifting symbolic structures, it is redefining the boundaries of human experience. More than three millennia ago, Odysseus reached the island of Circe, the sorceress who could turn men into beasts…
How does the brain organize our memories? A recent study suggests that slow brain rhythms may synchronize neural activity during encoding and recall, revealing a key temporal dimension of memory. Remembering a place, a route, or a familiar event feels effortless. However, beneath this apparent simplicity lies a highly complex orchestration of electrical signals. A…
Early screen exposure is more than a change in habits. It may affect the development of language, attention, and emotional regulation in children. Research is prompting a rethink of how screens are introduced in early life. It often begins harmlessly. A few videos to soothe a child after a difficult day, a cartoon to prepare…
Entre cortex et organes internes, un dialogue constant s’organise. L’émotion devient une régulation physiologique. For decades, neuroscience research has explored the boundaries between the brain and the body. How do thoughts, emotions, or stress influence heart rate, breathing, or digestion? While it was already known that certain brain regions, such as the hypothalamus or the…
Understanding how information becomes conscious remains one of neuroscience’s greatest challenges. A large-scale study confronting leading theories reveals a more complex reality than expected. Consciousness remains one of the greatest challenges in neuroscience. Every day we see, feel, and think, yet explaining how a mental content becomes conscious continues to elude us. Neuroscience has made…
How do our earliest emotional and sensory experiences shape not only the developing brain but also the deepest layers of our subjectivity, influencing our capacity to feel, think and create? Early childhood does more than shape memories, it builds the architecture of the brain itself.Through emotional interactions and neural development, it lays the foundations of…
