People who get musical training before the age of 7 form stronger connections in the brain than those who train later according to a new study.
Researchers at a Concordia University lab and the Montreal Neurological Institute of McGill University were surprised at the extent of the difference between the two. Those who trained earlier had stronger connections between motor regions. Those are the parts of the brain that help plan and carry out movements.
The study suggests that the time between ages six and eight are what the researchers call a “sensitive period.” During this time musical training interacting with brain development causes changes both in motor abilities and the actual structure of the brain. Playing a musical instrument requires a person to co-ordinate hands with visual or auditory stimuli. Reseachers think doing so before the age of seven boosts the connections in the areas of the brain needed to do that. They think those changes are long-lasting.
Each week, Eye on the Arctic turns its focus on the issues or people making a difference in Canada’s northern regions. Arviat, a predominantly Inuit community of 2800 people in Canada’s eastern Arctic territory of Nunavut, has long been plagued by the increasing number of rogue polar bears in the community.
Nobody is quite sure why the problem is becoming more common, but the worries it has created are shared by all residents.
Sled dogs and property have been attacked. And parents and locals have long been worried about the dangers the bears pose for people, especially children, in the community.
But a recent project put in place by the World Wildlife Fund and the Hamlet of Arviat called “The Human-Polar Bear Conflict Reduction Project” seems to be turning things around.
