When electrical activity travels across the brain, it moves like ripples on a pond. The motion of these "brain waves," first observed in the 1920s, can now be seen more clearly than ever before thanks ...

Gamma brain waves are rhythmic electric processes in nerve cells called neurons. Nerve activity in the brain allows for communication throughout the brain to carry out functions such as memory, ...

These wide-ranging waves quickly link the specific constellations of brain regions that work in harmony to perform a task. In the space of just a few seconds, a person walking down a city block might ...

The electrical signals rippling across the brain during and after physical activity offer a measurable window into how exercise reshapes mood. Researchers have spent decades recording ...

The brain’s cortex, which handles higher cognitive functions in mammals, is split into six distinct physical layers marked by varying cell types, sizes and connections—and new research suggests these ...

Have you ever put your keys down and then completely forgotten where to find them? The brain has to work hard to protect information in your working memory from distractions. How this process works ...
