All land mammals and birds have two types of sleep: rapid eye movement (REM) and non-REM (also called slow-wave sleep). Earlier evidence had suggested that REM sleep—associated with dreaming—is essential for physical ...

Behavioural sleep is ubiquitous among animals, from insects to man. In humans, sleep is also characterized by brain activity: periods of slow-wave activity are each followed by short phases of Rapid-Eye-Movement sleep (REM ...

(PhysOrg.com) -- The brain activity of ostriches in REM sleep is unique, alternating between fast, small waves - characteristic of REM sleep in other birds, and large, slow waves typical of those occurring during slow wave ...
