Sleep loss in Met-Val patients progresses more slowly, although they, too, ultimately lose deep-sleep stages, slow-wave EEG activity, and circadian motor rhythms. Nevertheless, body temperature ...

Some aspects of attention depend on frontal “Theta” frequency rhythms. For instance, our reaction times to simple stimuli are faster during a “good” phase of Theta and slower during a “bad” phase.

EEG signals of humans and canines showed that dogs' neural responses to speech are focused on slower 'delta' rhythms, while human responses to speech are focused on faster 'theta' rhythms.
