Brain fog can be scary. It might appear innocently, like losing your car keys or forgetting what date you scheduled that appointment on. Some of this memory loss is normal—it’s just a natural side ...

Parvalbumin (PV) interneurons act as the brain’s rhythm keepers. By regulating local circuit activity and maintaining excitation–inhibition balance, they help stabilize cortical network function. When ...

Scientists exploring how the brain responds to stress discovered molecular changes that can influence behavior long after an experience ends. They also identified natural resilience systems that help ...

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 have created a protein that can detect the faint chemical signals neurons receive from other brain cells. By tracking glutamate in real time, scientists can finally see how neurons process ...

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, ...
