People may count sheep when they cannot sleep, but when they do finally drift off their brains generate the same type of brain wave as their ovine counterparts, according to new research published in ...

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 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 ...

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 ...

During light slow-wave sleep, the thalamo-cortical network oscillates in waxing-and-waning patterns at about 7 to 14 Hz and lasting for 500 ms to 3 s, called spindles, with the thalamus rhythmically ...

How would you summarize your study for a lay audience? Our research focuses on sleep spindles—short bursts of brain activity during sleep that are crucial for stabilizing sleep and supporting memory.

Leading theories propose that sleep presents an opportune time for important, new memories to become stabilized. And it's long been known which brain waves are produced during sleep. But in a new ...

Sleep spindles helped predict recovery in unresponsive patients with acute brain injury. About a third of unresponsive patients showed well-formed sleep spindle patterns. Spindles frequently preceded ...
