 The brain is made up of two types of tissue, grey and white matter. Grey matter contains most of the nerve cells in the brain. These nerve cells, called neurons, carry information to and from different parts of the brain, including linguistic information. Studies have found that bilingual adults have denser gray matter than monolingual adults, especially in the left hemisphere, where language information is processed (Mechelli 2004). This effect is moderated by the age at which the second language was learned and the proficiency in the second language. Individuals who learned two language before the age of five had significantly denser gray matter, as did individuals who were more proficient in their second language, according to Mechelli (2004). The brain is made up of two types of tissue, grey and white matter.
