Why clowns can keep balls in air

PARIS: Neuroscientists have discovered that learning to juggle causes changes in white matter, the nerve strands which help different parts of the brain communicate with each other.

University of Oxford researchers recruited 48 healthy young adults who were unable to juggle and put them in a functional magnetic resonance imaging scanner to get a cross-section map of their brain.

Half the volunteers then underwent a six-week training period to learn how to juggle, during which they were also encouraged to practice for 30 minutes a day.
