New research on brain waves could help doctors treat cognitive decline.

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 ...

Traditional EEG brain wave measurements have been done in laboratory settings. Today, far simpler wireless headsets and headbands are available to consumers. The practice of companies quietly selling ...

Every 20 seconds, a wave of fresh cerebrospinal fluid rolls into the sleeping brain. These slow, rhythmic blasts, described for the first time in the Nov. 1 Science, may help explain why sleep is so ...

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 ...

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 ...

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 ...

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 team also found that errors triggered immediate changes in wave activity in the front region of the brain, which appeared to drive down alpha activity in the rear region. “It looks as if the brain ...
