Want to boost your memory ? Daily exercise is the key

New York: A long-term exercise regimen may help boost memory as it triggers a protein that enhances brain cell growth, a new study has found. “In humans who exercise consistently for four months, better performance on complex recall tasks, such as drawing from memory, is correlated with increased cathepsin B levels," van Praag added. "We also have converging evidence from our study that cathepsin B is unregulated in blood by exercise for three species -- mice, Rhesus monkeys and humans,” van Praag noted. For the study, published in the journal Cell Metabolism, the team compared memory recall in normal mice with that in mice lacking the ability to produce cathepsin B under both sedentary and running conditions.
