They're Not Just Birdbrains

London - Birds can sleep with one eye open and half their brains awake, researchers said today. The ability allows birds to detect approaching predators while still getting a bit of shut-eye. "They are able to make behavioural decisions about whether they keep one half the brain awake or allow both halves of it to sleep," Niles Rattenborg said.
The behavioural physiologist at Indiana State University in Terre Haute and his colleagues believe their research, published in the science journal, Nature, is the first evidence that an animal can control sleep and wakefulness simultaneously in different parts of the brain. Dolphins, seals and manatees also have the ability - known as unihemispheric slow-wave sleep - which allows them to sleep and swim to the surface to breathe, but Rattenborg said birds seem to be able to use it at will. "What was unique is that they are able to control it. They can also sleep with both halves of the brain. When they are sleeping under more risky situations they increase the proportion of their sleep with one eye open and half their brain awake," he said.
Rattenborg thinks the research could also have some implications for humans. Some sleep disorders, such as sleep walking, are thought to occur when parts of the brain wake up while other parts are still sleeping. "If birds can do it humans might be able to do it in some form or another," he said - Reuters
