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 ...

Billions of nerve cells send signals coursing through our bodies, serving as conduits through which the brain performs its essential functions. For millennia physicians thought damage to nerves was ...

Optogenetics has long been a powerful experimental tool, but a growing body of research suggests it may now be approaching a ...

Scientists created a model of the human pain pathway in a dish by connecting four separate brain organoids. The feat should help them understand sensory disorders like those affecting pain perception.

In recent years, many engineers have been trying to develop hardware components that could emulate the functions of various biological systems, including synapses, the human skin and nerves. These bio ...

Neural tissue engineering aims to mimic the brain's complex environment, the extracellular matrix, which supports nerve cell growth, development, and proper connectivity. This environment is carefully ...

In experiments with mice, Johns Hopkins Medicine scientists report new evidence that precursors of myelin-producing cells - one of the few brain cell types that continue to be produced in the adult ...

In order to understand brain diseases, neuroscientists try to untangle the intricate nerve fibre labyrinth of our brain. Before analysing brain tissue under a microscope, it is often soaked in ...

What unique processes conspire to create a healthy, functional human brain? How can we be so genetically similar to, say, chimpanzees, and yet be light-years more sophisticated cognitively and ...

The human body is full of elegant designs that seem almost too perfect to be real. But once in a while, nature throws in a ...
