The drugs disrupted communication between the brain and immune system to lower stress in mice. From depression to post-traumatic stress disorder, psychedelic drugs combined with therapy might ease symptoms. Once a counterculture outcast, these drugs are undergoing a renaissance in medicine for

The cables connecting neurons act like independent ‘mini-computers’ to store different types of information. The brain’s rules seem simple: Fire together, wire together. When groups of neurons activate, they become interconnected. This networking is how we learn, reason, form memories, and adapt to

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 disorder

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 boatload of

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
