Breath during sleep be a key component that helps the brain's memory hub do the best job possible to store and reinforce ...

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 ...

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 ...

A new Finnish study shows that individual circadian preference is associated with brain activity patterns during the night. Sleep spindles are bursts of oscillatory brain activity visible on an EEG ...

A new study suggests brain inflammation is the key factor linking sleep disturbances with Alzheimer’s disease. It's hypothesized the same overactive immune cells in the brain that ultimately ...

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) ...

In humans, some evidence suggests that there are two different types of spindles during sleep, which differ by their scalp topography and possibly some aspects of their regulation. To test for the ...

Want to teach an old dog new tricks? Try letting your pet take a nap. New research finds that dogs consolidate new memories in sleep, just like humans do. The study used electroencephalography (EEG), ...
