In Episode 33 we are joined by Dr. Liana Machado from the Department of Psychology at the University of Otago in New Zealand to chat about the effects of physical activity on cognition. Liana shares with us how exercise impacts brain blood flow and cognitive outcomes across the human life, especially in ageing. How does physical activity improve cognitive performance? What does brain blood flow tell us about how the brain functions? What kind of cognitive functions are benefitted by physical activity? All this and much more in The Brain on Exercise with Dr. Liana Machado!
