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 ...

Neuroscientists have been trying to understand how the human brain supports numerous advanced capabilities for centuries. The cerebral cortex, the outer layer of the brain, is now known to be ...

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

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 ...

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) ...

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

Scientists developed two new sensors that can detect brain cell communication in real time, tracking chemical messages ...

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, ...
