Musicians seem different than the rest of us; they seem to have astonishing memories and can multi-task better than non-musicians. Drummers, for example, seem to fly through complicated routines while their hands barely stop moving. New research has found that drumming actually changes the drummers’ brain structure.
Published in Brain and Behavior, this research focused on studying the brains of drummers with MRI (magnetic resonance imaging) to explore the changes that occur with the brain’s neuroplasticity when playing musical instruments. Previous studies of a similar nature had explored musical instruments, but none had focused specifically on drummers.
The researchers compared 20 musicians who had played drums for 17 years on average (and also spent more than 10 hours practicing each week) with 24 control participants who had no musical experience. Each group was asked to play drums while being monitored by the MRI.
The professional drummers showed distinct differences from the nonmusical control subjects in the area of the brain responsible for motor skills, specifically in the corpus callosum. The corpus callosum influences the planning of motor skills and is located between the two hemispheres of the brain. Drummers had thicker fibers contained in the corpus callosum which connected the two hemispheres of the brain. They had less fibers than the nonmusical subjects, but their fibers were much thicker. Thicker fibers mean that the drummers transmit information between the two hemispheres at greater speed than those with no musical experience.
Another difference between the brains of musicians and non-musicians was that the brain seemed to require less activity to produce these effects. The drummers’ brains were organized and able to run more efficiently in a pattern called “sparse sampling.” Their brains required less activity to produce the effects of motor planning and motor skills than those who were not professional musicians.
Drumming changes the brain in ways that can be measured, and drum circles can be mood boosters and produce beneficial psychological effects. It’s been part of the human experience since the first ancient humans produced drums.
