New research from the University of Wyoming reveals that the brain cells that control hunger may be far more adaptable during ...

Some older adults with exceptional memory grow far more new neurons in the hippocampus, while Alzheimer’s brains show almost ...

To stay in balance, the brain depends on two types of neurons: Excitatory neurons (in white), which increase activity, and inhibitory neurons (in black), which damp down signals. Scientists have now ...

A new study suggests AI systems could be a lot more efficient. Researchers were able to shrink an AI vision model to 1/1000th ...

Drug addiction carries an extremely high risk of relapse, as cravings can be reignited by minor stimuli even long after one has stopped using. Previously, this phenomenon was attributed to a decline ...

From Santiago Ramón y Cajal’s hand came branches and whorls, spines and webs. Now-famous drawings by the neuroanatomist in the late 19th and early 20th centuries showed, for the first time, the ...

When you get better at a skill-recognizing a familiar face in a crowd, spotting a typo at a glance, or anticipating the next move in a game-sensory neurons in your brain become more coordinated, ...

Most people wouldn’t give Geobacter sulfurreducens a second look. The bacteria was first discovered in a ditch in rural Oklahoma. But the lowly microbe has a superpower. It grows protein nanotubes ...

While neurogenesis—the growth of new brain cells—typically slows with age, superagers produce new neurons in the hippocampus at twice the rate of healthy older adults. In contrast, individuals with ...

MIT researchers have come up with a new idea about memory that highlights the role of astrocytes, a type of brain cell that’s often overlooked. The human brain is packed with around 86 billion neurons ...

Picture a star-shaped cell in the brain, stretching its spindly arms out to cradle the neurons around it. That's an astrocyte, and for a long time, scientists thought its job was caretaking the brain, ...
