Neural sleep patterns emerged at least 450 million years ago

Researchers at the Stanford University School of Medicine have found that neural signatures in sleeping zebrafish are analogous to those of humans, suggesting that the brain activity evolved at least 450 million years ago, before any creatures crawled out of the ocean. Scientists have known for more than 100 years that fish enter a sleeplike state, but until now they […]

Babies kicking in the womb are creating a map of their bodies

The kicks a mother feels from her unborn child may allow the baby to ‘map’ their own body and enable them to eventually explore their surroundings, suggests new research led by UCL in collaboration with UCLH. For the study, published today in Scientific Reports, researchers measured brainwaves produced when newborn babies kick their limbs during rapid eye movement (REM) sleep, […]

Children’s sleep not significantly affected by screen time, new study finds

Screen-time has little impact on the quality of children’s sleep, according to new Oxford University research. Screens are now a fixture of modern childhood. And as young people spend an increasing amount of time on electronic devices, the effects of these digital activities has become a prevalent concern among parents, caregivers, and policy-makers. Research indicating that between 50% to 90% […]
