The human brain is divided into two hemispheres, the right and left. The right side of the brain controls one’s creative thinking and expression while the left is used for mathematical and logical thinking. In regards to learning another language, both sides of the brain are used, switching from right to left. (1)
Throughout our daily activities the brain works to carry out every action and decision. The amount to which humans use their brains, thus working it out, in addition to the care provided for it (amounts of sleep) all factor into our brain densities. Recent studies conducted by Andrea Mechelli of London’s Wellcome Department of Imaging Neuroscience and colleagues, including experts from the Fondazione Santa Lucia in Rome, concluded that the bilingual brain develops more densely, giving it an advantage in various abilities and skills. (2)
Further studies have also proven that through learning and maintaining another language, people are less likely to get dementia and Alzheimers disease. (3)
Research has proven that although language is thought to be mediated by functional changes in the brain, they show that being bilingual structurally changes the brain. Their study shows the effect was strongest in people who had learned a second language before age 5 and that through continued practice of the language the brain continued to develop at a higher percent.

The longer students are exposed to foreign languages through the extended requirement will continue to shape their brain development and improve their ability to memorize information and be able to adapt to changes quicker.
