And while the technology sounds impressive now, it seems to be at the limits of what current laboratory photolithography can provide. At present, a 1 mm fibre chip can potentially integrate tens of ...

Over the past decades, computer scientists have developed increasingly advanced artificial intelligence (AI) systems that ...

The human brain contains billions of connected neurons that collectively support different mental functions, including the ...

Researchers discovered a feedback loop between nerve cells, the immune system and the heart. They think it shows promise as a ...

When a baby smiles at you, it's almost impossible not to smile back. This spontaneous reaction to a facial expression is part of the back-and-forth that allows us to understand each other's emotions ...

Neural circuits are refined by experience with higher plasticity at younger ages. Non-neuronal brain cells, known as astrocytes, were previously seen as passive support cells, but recent research has ...

A missing brain molecule may be disrupting neural wiring in Down syndrome, according to new research. Replacing it in adult mice rewired brain circuits and improved brain flexibility, challenging the ...

A Japanese research team has successfully reproduced the human neural circuit in vitro using multi-region miniature organs known as assembloids, which are derived from induced pluripotent stem (iPS) ...

Axons in the thalamus (pink) extended toward the cortex, while those in the cortex (green) extended toward the thalamus at 14 days post-fusion. A Japanese research team has successfully reproduced the ...

Washington State University researchers have discovered how a neural circuit – or a connection between two brain regions – drives relapse after opioid use, a finding that could lead to more effective ...

When engineers build AI language models like GPT-5 from training data, at least two major processing features emerge: memorization (reciting exact text they’ve seen before, like famous quotes or ...
