A little myelin goes a long way to restore nervous system function

In the central nervous system of humans and all other mammals, a vital insulating sheath composed of lipids and proteins around nerve fibers helps speed the electrical signals or nerve impulses that direct our bodies to walk, ...

A map of mouse brain metabolism in aging

The first atlas of metabolites in the mouse brain has been published by a team led by UC Davis researchers. The dataset includes 1,547 different molecules across 10 brain regions in male and female laboratory mice from adolescence ...
