The Brain and Aging

Dr. William Calvin, discusses theories of the brain. William H. Calvin, Ph.D. is an American theoretical neurophysiologist and professor at the University of Washington in Seattle. He is a well-known popularizer of neuroscience and evolutionary biology, including the hybrid of these two fields, neural Darwinism. He relates abrupt climate change to human evolution and more recently has been working on global climate change issues.

Dr. Jay Olshansky discusses the aging process. Stuart Jay Olshansky is a professor in the School of Public Health at the University of Illinois at Chicago concentrating on biodemography and gerontology. He is also a research associate at the Center on Aging and at the London School of Hygiene and Tropical Medicine. Olshansky is an associate editor of the Journal of Gerontology: Biological Sciences and Biogerontology and is a member of the editorial boards of several other scientific journals. Olshansky has been working with colleagues in the biological sciences to develop the modern “biodemographic paradigm” of mortality – an effort to understand the biological nature of the survival and dying out processes of living organisms. The focus of his research has been on estimates of the upper limits to human longevity, exploring the health and public policy implications associated with individual and population aging, forecasts of the size, survival, and age structure of the population, pursuit of the scientific means to slow aging in people, and global implications of the re-emergence of infectious and parasitic diseases, and insurance linked securities.
