Research Sheds Light on How Our Nerves Keep Firing

The way in which nerve cells recycle tiny bubbles or "vesicles" that send chemical nerve signals from one cell to the next has been identified by University of Utah and German biologists. The process is much faster and different than two previously proposed mechanisms for recycling the bubbles. Researchers photographed mouse brain cells using an electron microscope after flash-freezing the cells in the act of firing nerve signals. That showed the tiny ...
