Final answer:
Exercise can increase the size of the hippocampus and prefrontal cortex, leading to a 'smarter' brain.
Explanation:
The parts of the brain that can get bigger with exercise and provide protective effects on the brain include the hippocampus, part of the limbic system involved in learning and memory, and the prefrontal cortex, responsible for higher-level cognitive functions such as problem-solving and planning.
Sustained aerobic exercise like running has been linked to increased neurogenesis in the hippocampus, potentially leading to a 'smarter' brain
Consistent physical exercise induces positive changes in brain structure and cognitive function.
