"Structural brain adaptations in musicians have been repeatedly demonstrated in areas involved in auditory perception and motor skills. However, musical activities are not confined to auditory perception and motor performance, but are entangled with higher-order cognitive processes."
The US National Library of Medicine and National Institute of Health has found that increased levels of gray matter are seen with musical training. These cognitive changes implicate reasons to believe that music implicated in experience-dependent plasticity may relate to executive functioning elements of cognition and regional connectivity.
