Studies of identical twins can provide good answers

In another entry related to the neuroscience of aging, I cited a study by Heflin et al on the significantly negative mental consequences of surviving cancer and its treatments. This “twins study” was one of a series of such experiments that have come from the University of Southern California research team of Margaret Gatz. Her group’s research is a good starting point for learning about environmental contributors to cognitive deficits and senility, because studies conducted in identical twins (she relies heavily on a large Swedish identical-twin roster) eliminate known contributions of genetics and child rearing and education to aging successes and risks. The post Studies of identical twins can provide good answers appeared first on "On the Brain" with Dr. Michael Merzenich.
