(PhysOrg.com) -- Scientists studying cognitive decline that accompanies aging have been interested in nicotinic receptors, part of a key neural pathway that not only enhances learning and memory skills but reinforces addictions as well. The loss of these receptors has been difficult to study in living subjects, but Yale University researchers using advanced imaging technology have successfully tracked the loss of receptors with age, according to a report in the September issue of the journal Neurobiology of Aging.
