Neuroscientists and psychologists have been trying to understand how the human brain supports learning and the encoding of ...

Researchers identify "meal memory" neurons in laboratory rats that could explain why forgetting lunch leads to overeating. Scientists have discovered a specific group of brain cells that create ...

Age-related memory decline and neurodegenerative diseases like Alzheimer’s are often thought of as irreversible. But the brain is not static; neurons continually adjust the strength of their ...

“If we go back to the early 1900s, this is when the idea was first proposed that memories are physically stored in some location within the brain,” says Michael R. Williamson, a researcher at the ...

Astrocytes, once thought to be mere brain “support cells,” are now revealed to be key players in fear memory. Researchers found they actively help form, recall, and weaken fear responses by ...

We often think of memory as stable—a mental archive that stores experiences in neat, retrievable files. But what if those files quietly shift positions, even when the original experience hasn’t ...

For the millions of people who carry the gene APOE4, the strongest known genetic risk factor for Alzheimer's disease, their ...

Age can make memory feel like something that only moves in one direction. A name slips away. A route you know well turns fuzzy. In Alzheimer’s disease, that slide can look even steeper. Yet the brain ...
