Sleep Could Produce Cells That Protect The Brain's Circuitry

A study in the Journal of Neuroscience says that sleep could produce the cells that create the insulating material known as myeline. The findings are only in mice so far, but may lead to treatment for those with Multiple Sclerosis. The production increased most during REM. It makes me wonder how many more benefits there are to sleep that science hasn't found yet.

Scientists Predict Images in Dreams

Japanese scientists were able to predict what images people saw in their dreams using MRI scans, according to BBC News.  They accomplished 60% accuracy.

Who knows, this could eventually lead to a machine that we could hook up to and report what we saw in our dreams.  It could be an interesting way to jog the brain to remember the dreams from the previous night.
