After 48 hours, the participants' memory was tested while their brains were scanned*4 via MRI*5. Those who exercised four hours after the learning session retained*6 information better than the other two groups. The MRI also showed the hippocampus, the brain region involved with learning and memory, - that (2) 15 was more active when information was recalled correctly. Newly learned information turns into long-term knowledge through a process that requires certain brain chemicals that are released during exercise, but more research is needed to understand (3) this phenomenon.
