A team of neuroscientists has restored lost memory function in cognitively impaired mice by flipping a molecular switch inside the animals’ neuronal mitochondria, the microscopic structures that ...

Cedars-Sinai researchers created “young” immune cells from human stem cells that reversed cognitive decline and Alzheimer’s symptoms in mice. The treated animals showed better memory and healthier ...

Researchers have reversed memory loss in aging mice by targeting a protein that builds up in brain cells, pointing toward a potential pathway to counter the cognitive declines of aging. In a new study ...

In mice, a brain protein called Arc helps spread toxic molecules from sick brain cells to healthy ones. If therapies could be ...

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 ...

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." The brain may lie at the biological center of our lived experience, but the scientific underpinnings of ...

Researchers have identified a molecular mechanism that helps explain why growing up in a stimulating environment enhances memory. In contrast, a lack of stimulation can impair it. The team from the ...

New experiences are integrated with existing knowledge to update memory, which is essential for survival in a dynamic environment. Despite this updating, the brain can still access previous memories ...

Scientists have discovered that a very small group of brain cells deep inside the brain may play a major role in anxiety, ...
