Learning languages is a workout for the brain, for young and old. Learning a new language, in fact, change the network brain both structurally and functionally, according to recent studies. "Learn and practice something, for example, a second language, strengthens the brain," said Li Ping, professor of psychology, linguistics and information science and technology. "How to exercise, the more you use specific areas of the brain, the more it grows and becomes stronger."

Li and colleagues studied 39 brains of people native English speakers: over a period of six weeks, pledged to study the Chinese vocabulary. Subjects busy learning new vocabulary, those who were most effective in reaching the information showed a brain network more complex.

The researchers also found that participants who were successful students have had a network connected most of the other participants, even before the experiment of learning the Chinese language. A network better integrated brain is more flexible and efficient, making the task of learning a new language easier. Li and his colleagues reported their findings in a recent article published in the Journal of Neurolinguistic.

The efficiency of brain networks was defined by researchers in terms of strength and direction of the connections, or edges, between brain regions of interest, or nodes. The stronger the edges that go from one node to another, faster nodes can work together, and the network is more efficient.

Participants underwent two fMRI scans - a first experiment and after - so that the researchers could track changes neural. At the end of the study period, the researchers found that the brains of successful students had undergone functional changes - the brain network was better integrated.

These changes are in line with the anatomical changes that may occur in the brain as a result of learning a second language, no matter the age of the student, as reported in a recent issue of Cortex.

"A very interesting result is that, contrary to previous studies, the brain is much more plastic than we thought," said Li, "We can still see anatomical changes in the brain in the elderly, which is very encouraging news for aging. And learning a new language can help lead to an aging sweeter. "

Meanwhile, Li and colleagues have started working on ways to teach a language interactive virtual environments using 3-D, a situation that seems to help the brain to make some of these new more effective links.
