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 ...

Memories are thought to be stored in sparse groups of neurons called engrams. These are the cells that switch on during learning and can later switch on again during recall. In physiological aging and ...

Resting brain stem cells hardly differ from normal astrocytes, which support the nerve cells in the brain. How can almost identical cells perform such different functions? The key lies in the ...

A mechanism underlying neutrophil reprogramming in brain cancers has been uncovered, illuminating potential therapeutic targets to stop their pro-cancer effect. Tumor-infiltrating neutrophils are ...

The lab of Filippo Veglia, Ph.D., at The Wistar Institute has discovered a previously unknown mechanism for how aggressive brain cancers reprogram immune system cells from fighting cancer to enabling ...

When a neuron ages, it loses synaptic connections with other neurons, it is less able to transmit nerve impulses, and its metabolism is also altered. This process of neuronal ageing — inevitable with ...

The human brain has 86 billion neurons connected by roughly 100 trillion synapses, making it one of the most complex objects in the known universe. Each year neuroscientists make fascinating, ...

Neurologists are exploring medications that would help the brain recover after a stroke or traumatic injury. Credit...Fabio-Consoli Supported by By Rachel E. Gross The first thing Debra McVean did ...
