Researchers in Japan built a miniature human brain circuit using fused stem-cell–derived organoids, allowing them to watch the thalamus and cortex interact in real time. They found that the thalamus ...

Scientists are developing a "sponge" that can soak up pain signals in the body before they reach the brain, potentially ...

As prominent artificial intelligence (AI) researchers eye limits to the current phase of the technology, a different approach is gaining attention: using living human brain cells as computational har ...

The human brain can do many amazing things, but self-repair is not one of its repertoire of abilities. Once neurons die—from trauma, stroke, or disease—they rarely grow back. Scientists have been ...

Some parts of our bodies bounce back from injury in fairly short order. The outer protective layer of the eye—called the cornea—can heal from minor scratches within a single day. The brain is not one ...

Just a few weeks after conception, stem cells are already orchestrating the future structure of the human brain. A new Yale-led study shows that, early in development, molecular “traffic cops” known ...

A stem cell therapy for stroke restored neuron function and revealed how transplanted cells navigate the nervous system.

The brain's mechanisms for repairing injuries caused by trauma or degenerative diseases are not yet known in detail. Now, a study from the University of Barcelona describes a new strategy based on ...

The human brain is a fascinating and complex organ that supports numerous sophisticated behaviors and abilities that are observed in no other animal species. For centuries, scientists have been trying ...
