The mind of the polyglot is a very particular thing, and scientists are only beginning to look closely at how acquiring a second language influences learning, behavior and the very structure of the brain itself.
When we learn another language the structure of our brain is changed. That change leads to a greater efficiency of use in the brain. The brain is better organized and uses it’s energy in a more conservative way in comparison to a monolingual brain. Studies also suggest that multi-(bilingualism) boosts the so-called executive function of the brain. This command system is responsible for planing, solving problems and performing tasks. In order to stay focused, distractions have to be ignored and important information must be kept in mind.
