Arts Appear To Play Role In Brain Development

Classes Can Change Brain And The Way People Think

For years, school systems across the nation dropped the arts to concentrate on getting struggling students to pass tests in reading and math. Yet now, a growing body of brain research suggests that teaching the arts may be good for students across all disciplines.

Scientists are now looking at, for instance, whether students at an arts high school who study music or drawing have brains that allow them to focus more intensely or do better in the classroom.

Washington County schools Superintendent Betty Morgan would have liked to have had some of that basic research in her hands when she began building a coalition for an arts high school in Hagerstown. The business community and school principals worked together, and the school will open this summer, but even at its groundbreaking a man objecting to the money spent on the school held up a sign of protest reading "Big Note$ Wrong Music."

Scientists and educators aware of the gap between basic research and the school systems are beginning to share findings, such as at this month's seminar on the brain and the arts held at Baltimore's American Visionary Art Museum.

The event was sponsored by the new Neuro-Education Initiative at the Johns Hopkins University, a center designed to bridge that gap.

Brain research in the past several years is just beginning to uncover some startling ideas about how students learn. First came the proof, some years ago, that our brains do not lose brain cells as we get older, but are always capable of growing.

Now neuroscientists are investigating how training students in the arts may change the structure of their brains and the way they think. They are asking: Does putting a violin in the hands of an elementary school student help him to do math better? Will learning to dance or paint improve a child's spacial ability or ability to learn to read?

Research in those areas, Harvard professor Jerome Kagan said, is "as deserving of a clinical trial as a drug for cancer that has not yet been shown to be effective."

There aren't many conclusions yet that can be translated into the classroom, but there is an emerging interdisciplinary field between education and neuroscience. Like Hopkins, Harvard also has created a center to study learning and the brain.

Much of the research into the arts has centered on music and the brain. One researcher studying students who go to an arts high school found a correlation between those who were trained in music and their ability to do geometry. Yet another four-year study, being conducted by Ellen Winner of Boston College and Gottfried Schlaug of Harvard, is looking at the effects playing the piano or the violin has on students who are in elementary school.

Winner said she was quite skeptical of claims that schools that had introduced the arts had seen an increase in test scores and a generally better school climate. She had previously looked at those claims and found they couldn't be backed up by research.

However, she is in the midst of a four-year study of elementary students that has shown some effects: One group is learning an instrument and another is not. "It is the first study to demonstrate brain plasticity in young children related to music playing," Schlaug said.

The study Winner is working on has shown that children who receive a small amount of training - as little as half an hour of lessons a week and 10 minutes of practice a day - do have structural changes in their brains that can be measured. And those students, Winner said, were better at tests that required them to use their fingers with dexterity.

About 15 months after the study began, students who played the instrument were not better at math or reading, although the researchers are questioning whether they have assessments that are sensitive enough to measure the changes. They will continue the study for several more years.

Charles Limb, a Johns Hopkins doctor and a jazz musician, studied jazz musicians by using imaging technology to take pictures of their brains as they improvised. He found that they allowed their creativity to flow by shutting down areas that regulated inhibition and self-control. So are the most creative people able to shut down those areas of the brain?

Most of the new research is focusing on the networks of the brain that are involved in specific tasks, said Michael Posner, a researcher at the University of Oregon. Posner has studied the effects of music on attention. What he found, he said, was that in those students who showed motivation and creativity, training in the arts helped develop their attention and their intelligence. The next great focus in this area, he said, is on proving the connection that most scientists believe exists between the study of music and math ability.

The imaging is now so advanced that scientists can already see the difference in the brain networks of those who study a string instrument and those who study the piano intensely.
