New sleep research links two measurable brain-wave patterns during deep sleep to sharper thinking, no matter how many hours ...

When and how we sleep seems to be linked to our cognitive ability.

Michael J. Prerau, Ph.D., of the Division of Sleep and Circadian Disorders at Brigham and Women's Hospital, is the senior author of a paper published in Proceedings of the National Academy of Sciences ...

As we make the transition from stage 1 to stage 2 sleep a number of changes occur in the EEG that signal the increasing depth of sleep. Two prominent markers of stage 2 sleep are K complexes and sleep ...

A new study shows that sleep spindles, brief bursts of brain activity occurring during one phase of sleep and captured by EEG, may regulate anxiety in people with post-traumatic stress disorder (PTSD) ...

Distinctive bursts of sleeping-brain activity, known as sleep spindles, have long been generally associated with strengthening recently formed memories. But new research has managed to link such ...

Researchers have characterized how spindle detection parameter settings influence the association between spindles and cognition, and they identified parameters that best correlate with cognitive ...

Here’s something neat about sleeping sheep: Their brains have fast zags of neural activity, similar to those found in sleeping people. Here’s something even neater: These bursts zip inside awake sheep ...

People whose sleep brain waves register as biologically older than their actual age face a sharply elevated risk of ...
