Recognition that aging is not the accumulation of disease, but rather comprises fundamental biological processes that are amenable to experimental study, is the basis for the recent growth of experimental biogerontology. As increasingly sophisticated studies provide greater understanding of what occurs in the aging brain and how these changes occur, new possibilities emerge for limiting the effects of aging on neural function. Outlining the newest methods and techniques, Brain Aging: Models, Methods, and Mechanisms provides scientists, researchers, and clinicians with a broad understanding of the important progress and implications for the future of this important field.
