Researchers in Japan built a miniature human brain circuit using fused stem-cell–derived organoids, allowing them to watch ...

The simplified approach makes it easier to see how neural networks produce the outputs they do. A tweak to the way artificial neurons work in neural networks could make AIs easier to decipher.

Researchers have engineered a next-generation glutamate sensor, iGluSnFR4, capable of detecting the faintest incoming ...

Both, human brain and modern artificial neural networks are extremely powerful. At the lowest level, the neurons work together as rather simple computing units. An artificial neural network typically ...

When a house catches on fire, we assume that a smoke alarm inside will serve one purpose and one purpose only: warn the ...

Working in a mouse model, UC Davis researchers are able to distinguish brain cells activated by a psychedelic drug. This image shows the prefrontal cortex of a mouse injected with scFLARE2 (purple) ...

For the past decade, AI researcher Chris Olah has been obsessed with artificial neural networks. One question in particular engaged him, and has been the center of his work, first at Google Brain, ...

Natural physical networks are continuous, three-dimensional objects, like the small mathematical model displayed here.

Scientists have identified previously unknown neural modules in the brain that control movement and adapt during skill learning. Their findings challenge long-held ideas about how the brain organizes ...
