Music Lessons Early in Life May Help Preserve Brain Function with Age

Canadian team reports that taking music lessons before the age of 7 years helps to create stronger connections in the brain.

Previous research suggests that training during a sensitive period in development may have greater effects on brain structure and behavior than training later in life.  Virginia Penhune, from Concordia University (Canada), and colleagues tested 36 adult musicians on a movement task, and scanned their brains. Half of these musicians began musical training before age seven, while the other half began at a later age, but the two groups had the same number of years of musical training and experience. These two groups were also compared with individuals who had received little or no formal musical training.  When comparing a motor skill between the two groups, musicians who began before age seven showed more accurate timing, even after two days of practice. When comparing brain structure, musicians who started early showed enhanced white matter in the corpus callosum, a bundle of nerve fibres that connects the left and right motor regions of the brain. Importantly, the researchers found that the younger a musician started, the greater the connectivity.  The study authors conclude that:  “We propose that training before the age of 7 years results in changes in white-matter connectivity that may serve as a scaffold upon which ongoing experience can build.”
