Two studies found stem-cell therapies were safe and reduced symptoms, but bigger trials are still needed. Grabbing a coffee cup seems easy. But you need to be able to move your hand, stretch it out, and keep it steady. These movements are difficult for people with Parkinson’s disease. The

In a first, the 3D reconstruction of a mouse brain links structure to activity. Let a mouse nose around a house, and it will rapidly find food and form a strategy to return to it without getting caught. Given the same task, an AI would require millions of training examples and consume a

The thalamus is a gateway, shuttling select information into consciousness. How consciousness emerges in the brain is the ultimate mystery. Scientists generally agree that consciousness relies on multiple brain regions working in tandem. But the areas and neural connections supporting our

Our closest relatives in the animal kingdom are wired up differently. Scientists have long tried to understand the human brain by comparing it to other primates. Researchers are still trying to understand what makes our brain different to our closest relatives. Our recent study may have brought

The system, which also synthesizes her voice, takes no more than a second to translate thoughts to speech. A paralyzed woman can again communicate with the outside world thanks to a wafer-thin disk capturing speech signals in her brain. An AI translates these electrical buzzes into text and,
