A baby's brain is a work in progress, trillions of neurons waiting to be wired into a mind. The experiences of childhood, pioneering research shows, help the brain's circuits--for music and math, language and emotion
MUSIC AND NEURAL CIRCUITS
Last October researchers at the University of Konstanz in Germany reported that exposure to music rewires neural circuits.
In the brains of nine string players examined with magnetic resonance imaging, the amount of somatosensory cortex dedicated to the thumb and fifth finger of the left hand - the fingering digits - was significantly larger than in non players.
How long the players practiced each day did not affect the cortical map. But the age at which they had been introduced to their muse did: the younger the child when she took up an instrument, the more cortex she devoted to playing it.
