Want to think about a real nightmare? Imagine a virus like the one that causes AIDS, which leaves the host alive and able to spread the disease for years before he or she dies.

The most likely villains now appear to be a group of < previous page page_19 next page > < previous page page_20 next page > Page 20 chemicals known as free radicals, which are a normal byproduct of basic metabolism (as well as of other processes). These chemicals, once free in the cell, break down molecules needed for cell repair and, in some cases, DNA itself. A striking bit of evidence pointing to free radicals as the mechanism of aging is that animals with high metabolism rates (and hence high rates of free-radical production) tend to have shorter lives and to produce fewer chemicals to combat the free radicals.

This is the cerebral cortex, the outer covering of the brain. Today, using a new technique called functional magnetic resonance imaging (fMRI), scientists are learning how this quintessentially human organ works.
