When music and long-term memory interact: effects of musical expertise on functional and structural plasticity in the hippocampus.

The development of musical skills by musicians results in specific structural and functional modifications in the brain. Surprisingly, no functional magnetic resonance imaging (fMRI) study has investigated the impact of musical training on brain function during long-term memory retrieval, a faculty...
