Can You Supercharge Your Brain?

Your brain is the finely-tuned machine that controls all your actions and emotions, so it makes sense to keep it well-oiled. But, asks Rita Carter, are there any scientifically proven methods to ensure it works better for longer?

Learn A Language Or Instrument

So far only two types of mental exertion have been shown to improve or preserve overall cognitive ability. One is musical training; the other is learning a new language, or practising a second one you have already learned.

Gottfried Schlaug, director of the Music and Neuroimaging Laboratory at Harvard University, the USA, explains: “Listening to and making music is not just an auditory experience; it’s a multisensory and motor experience. Playing an instrument changes how the brain interprets and integrates a wide range of sensory information, and making music over a long period of time can change brain function and brain structure”

As for the role of language-learning in boosting brain power, a team at Edinburgh University assessed mental alertness in a group of 33 students (aged 18 to 78) who undertook a one-week Scottish Gaelic course. After the course, they were encouraged to practise their new language for five hours a week. At the end of the course, their attention was found to be better than comparison groups who had done other types of courses or no course at all, and, nine months later, those who had been practising had bumped up their attention span even more.
