Most of the tasks that humans complete daily entail carefully coordinating movements and tracking progress made toward a ...

Fear memories can form in the brain following exposure to threatening situations such as natural disasters, accidents, or violence. When these memories become excessive or distorted, they can lead to ...

What neural and behavioral mechanisms allow mice to identify food sources, navigate toward them, and initiate consumption? A research team led by Prof. Zhang Yunfeng from the Institute of Zoology of ...

The brain of humans and other animals is known to contribute to the protection of the body from infections. Past studies have unveiled the existence of the so-called conditioned immune response (CIR), ...

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 ...

Because unpleasant withdrawal symptoms fuel nicotine addiction’s high relapse rate, targeting their underlying mechanisms with treatments may promote continued abstinence from the drug. In a new ...

Stanford Medicine investigators have replicated, in a lab dish, one of the most prominent human nervous pathways for sensing pain. This nerve circuit transmits sensations from the body’s skin to the ...

For the first time, scientists have generated a functional neural pathway for sensing pain in a dish. This could help unravel mechanisms of pain disorders. “This is important groundbreaking work,” ...
