Bilingualism effects on the brain


Have you ever wondered how bilingualism effects the brain? Recent studies have demonstrated that there are several things that occur differently in a bilingual brain. The posterior parietal lobe appears to be larger among bilinguals, this section of the brain is related to the acquisition of a second language. This section is more stimulated if the second language is learned at a younger age. The process to acquiring a language is different when learning a second language at a different stage of your life. Studies have also demonstrated that certain words in the second language, are able to activate brain areas, such as the motor and premotor cortex. These areas in the brain are stimulated only during physical activities, demonstrating a union between the body and language. Bilingualism in the long run has demonstrated benefits in learning but it also displays cognitive reserve for later on in life, which will delay the onset of Alzheimer’s disease.
