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 ...

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.

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 ...

Sleep strips away consciousness, but it does not shut the brain down. PET imaging of 37 volunteers has shown that regional ...

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) ...

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 ...
