Researchers at Johns Hopkins University have discovered a group of neurons in an ancient brain region that helps filter distractions and maintain focus. Experiments in mice showed that temporarily disabling these cells led to increased distractibility similar to symptoms seen in ADHD.

The family of former NHL player Claude Lemieux has decided to donate his brain to Boston University for research into the long-term effects of repeated head injuries.

Researchers have engineered a protein that detects subtle glutamate signals between neurons, unveiling a previously hidden aspect of brain communication. This tool allows real-time observation of how brain cells process incoming information, potentially advancing studies on learning, memory, and neurological disorders. The findings, published in Nature Methods, highlight a breakthrough in neuroscience.

Neuroscientists have identified eight body-like maps in the visual cortex that mirror the organization of touch sensations, enabling the brain to physically feel what it sees in others. This discovery, based on brain scans during movie viewing, enhances understanding of empathy and holds promise for treatments in autism and advancements in AI. The findings were published in Nature.

Scientists at The Ohio State University have charted how patterns of brain wiring can predict activity linked to many mental functions across the entire brain. Each region shows a distinct “connectivity fingerprint” tied to roles such as language and memory. The peer‑reviewed findings in Network Neuroscience offer a baseline for studying healthy young adult brains and for comparisons with neurological or psychiatric conditions.

Researchers at MIT’s Picower Institute report that rotating waves of neural activity help the brain recover focus after distraction. In animal studies, the extent of these rotations tracked performance: full rotations aligned with correct responses, while incomplete cycles were linked to errors. The timing between a distraction and response also mattered, suggesting a timing‑dependent recovery cycle.
