Chuck Bednar for redOrbit.com - Your Universe Online Researchers from the Harvard School of Medicine and the University at Buffalo School of Medicine and Biomedical Sciences have discovered a region of the brain responsible for causing people to fall into a deep sleep. This slumber-promoting circuit, which is located deep in the primitive brainstem, is only the second such “sleep node” ever discovered in the brains of mammals, the study authors said. In research published online...

Brett Smith for redOrbit.com - Your Universe Online Previous research has shown that the brain strengthens and maintains recently acquired memories during sleep and a new study has found that introducing new memories to a sleeping brain disrupts these natural cognitive processes.

However, it was...

Sleep Better And Improve Your Memory With Sound Stimulation

April Flowers for redOrbit.com - Your Universe Online A new study reveals that the slow oscillations in brain activity that occur during slow-wave sleep are critical for retaining memories. Playing sounds synchronized to the rhythm of the slow brain oscillations of sleeping people enhances the oscillations, the researchers found, and boosts memory retention. The study, published in Neuron, demonstrates an easy and noninvasive method of influencing human brain activity to improve sleep...

The findings suggest an explanation for the association between sleep problems and obesity. Researchers from St. Luke's-Roosevelt Hospital and Columbia University investigated the effects of sleep architecture on hunger to determine whether...
