Training your brain: Do mental and physical (MAP) training enhance cognition through the process of neurogenesis in the hippocampus?

► Mental or physical training increase hippocampal neurogenesis and facilitate learning. ► Neurogenesis is required for some, but not all, cognitive enhancing effects of training. ► Mental training has its greatest effect when difficult, but attainable. ► Larger effects may be observed following a combination of both mental and physical (MAP) training.
