Tune Your Engine - Dr. Kirk Erickson

Want to improve your memory? Take a hike. Or a stroll, even. A new study suggests that regular walking can improve and maintain the hippocampus- the part of the brain that makes memories. In a study published in the US last month, researchers took two groups of men and women in their sixties, one group was set to walking three times a week, the other group did different activities. After a year, the brains of the walkers had altered, and their hippocampus in particular had increased in volume. In the other group, meanwhile, the hippocampus had declined. Dr. Kirk Erickson is an Associate Professor at the Department of Psychology at the University of Illinois, and the Lead Author of the study.
