The human brain contains roughly 86 billion neurons, and for decades scientists have assumed that these cells are the primary ...

When a new memory forms the brain undergoes physical and functional changes known collectively as a “memory trace.” This memory trace represents the specific patterns of neuronal activity and ...

As far back as Plato and Aristotle, people believed that our memories had to be physical somethings that were stored somewhere in the brain. But only in modern times have we learned much about what ...

For decades, textbooks told students the human brain held roughly 100 billion neurons and that glial cells outnumbered them ...

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 ...

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 ...

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 ...

Alzheimer's disease is a neurodegenerative disease characterized by a progressive decline in mental functions and memory loss. Along with frontotemporal dementia and some other neurodegenerative ...
