Mitochondria, the tiny organelles without which our bodies would be deprived of energy, are gradually revealing their mysteries. In a new study published in Nature Neuroscience, researchers from Inserm and the University of Bordeaux at the NeuroCentre Magendie, in collaboration with researchers from the Université de Moncton in Canada, have for the first time succeeded in establishing a causal link …

Summary: Researchers studying people with epilepsy have discovered that nerve cells in the medial temporal lobe coordinate their firing with slow brain waves to encode and retrieve memories. This synchronization, known as theta-phase locking, occurs at one to ten cycles per second and is active during both learning and recall. The strength of this rhythm during memory formation did not …

Elena Rybakina must have figured she had the match won. She’d just battered 18-year-old Victoria Mboko in a 25-shot rally late in their Montreal semifinal, sending her sprinting from corner to corner until Mboko’s desperate lob drifted long. Mboko hunched over in exhaustion afterwards, her racket pressed hard into the ground as a crutch. Losing a miserable point like this, …

Summary: Some people feel absolutely nothing when listening to music—and not because of bad taste. A rare condition called specific musical anhedonia involves a disconnect between the brain’s auditory and reward systems, making music emotionally flat even though other rewards like food or money still trigger pleasure. New insights from researchers explore how this condition reveals the nuanced ways our …

A donated SuperAger brain at Northwestern University in Chicago, IL. Shane Collins, Northwestern University hide caption toggle caption Shane Collins, Northwestern University The human brain tends to slow down as we age — even healthy brains shrink. That can make learning and memory harder as people age. But some people’s brains shrink more slowly than their peers. This lucky group is …

In a major new finding almost a decade in the making, researchers at Harvard Medical School say they’ve found a key that may unlock many of the mysteries of Alzheimer’s disease and brain aging — the humble metal lithium. Lithium is best known to medicine as a mood stabilizer given to people who have bipolar disorder and depression. It was …
