Bilingual and monolingual brain

       Learning a foreign language is a challenge because it is a process that is slowly changing the way our brain works although at first glance it seems ordinary. The bilingual brain is not the same as the monolingual one. Neither physiological nor functional. Speaking more than one language causes the brain to work differently, to activate different neuronal areas and to increase the density of white matter, the insulating substance that covers the nerve connections.

   Over the years scientists have studied the process of language acquisition of which many theories already exist such as the Innatism created by Noam Chomsky.  Based on  this and another theories, scientists at the University of Pompeu, Spain, have discovered that a bilingual brain develops certain parts of it focused on language control while a monolingual brain only works on language-oriented parts.

   Actually the main difference between a monolingual and a bilingual brain is in its ability to make decisions. It is not that some are more intelligent than others, but that they develop another set of skills. For example, bilinguals develop cognitive abilities that allow them to adapt to changes in the tasks they are developing. This is because your brain is constantly choosing the language in which it is expressed, which gives it much more flexibility. It also allows them to concentrate and memorize better.  Generally people believe that bilinguals are smarter than monolinguals; however, this is not scientifically proven since the only thing that science can affirm is that learning another language can prevent many diseases such as Alzheimer's.

    In conclusion, a bilingual brain has the ability to quickly adapt to changes since certain different parts work at the same time, that is, it can easily differentiate each language without complicating when it has already adapted to it while the brain of a monolingual person only works the necessary parts to speak your native language.
