Brain Waves at Night: The Key to Preventing Alzheimer’s and Parkinson’s?

 Sleep contains a paradox. In contrast to the frantic activity going on in the brain, it appears to be rather calm.

  Even if the night is quiet, the mind is anything but.

 When we sleep, our brain cells are at their most active, producing electrical pulses that build up into rhythmic waves.

 Calm, rejuvenating slumber is characterized by slow brain waves. 

  Louis's Washington University School of Medicine have discovered that while we sleep, our brain waves aid in eliminating waste.

 In order to wash the dense brain tissue, individual nerve cells work together to generate periodic waves that push fluid through the tissue.

 Miniature pumps, these neurons are. The first author, a postdoctoral research associate in the Department of Pathology & Immunology named Li-Feng Jiang-Xie, PhD,,,

 noted that the brain's fluid flow and debris elimination are powered by synchronized neuronal activity.
