Loss and dysfunction of synapses have been linked to age-related cognitive decline and observed in Alzheimer's and other ...

The cerebral cortex, the brain’s outermost region responsible for higher cognitive functions, depends on a highly ordered, ...

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 ...

Recent work has revealed some of the many crucial functions of astrocytes, brain cells that were once thought to play primarily supportive roles for neurons. Astrocytes do handle debris around neurons ...

A Harvard-discovered protein called REST appears to act as a neural bodyguard in the brains of people who stay cognitively ...

Understanding the connection between behavior and brain cell activity is a major goal of neuroscience. To make progress, ...

Scientists have discovered a specific group of brain cells that create memories of meals, encoding not just what food was eaten but when it was eaten. The findings, published in Nature Communications, ...

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 ...

Johns Hopkins scientists say they have used 3D imaging, special microscopes and artificial intelligence (AI) programs to ...

Unlearning fear responses is a fundamental learning process in the brain. It allows us to flexibly react to formerly ...
