Jugglers Change Their Brains in Seven Days

In The Problem of Time I discussed the speed at WyyMi might be effective. A big question is how much training and practice of coordination skills is required before your brain adapts. In the case of juggling, the answer appears to be within seven days.

After only 7 days, a motion specialised part of the occipital lobe known as V5 had increased in density. In both studies, the changes were maintained over the subsequent weeks of practice, but these areas returned to their pre-learning state after several weeks without juggling.
