Science is being published that shows how brain exercise can lead to enhanced neuroplasticity (growth of new neurons and connections between them) throughout life.Answer:Although some knowledge about the brain has been around since the days of Ancient Greece and Rome, it really got a boost in the 19th century with some major discoveries in brain localization.... Yet, due to technical and economic constraints, many of the tools to understand cognition stayed within university, medical, and military research labs where they were inaccessible to most people.With recent scientific developments, it has become much easier and cheaper to learn more.
