Although some of these multiregional differences could be attributable to innate predisposition, the authors believe they may represent structural adaptations in response to long-term skill acquisition and the repetitive rehearsal of those skills.

The authors note that musicians learn complex motor and auditory skills (e.g., the translation of visually perceived musical symbols into motor commands with simultaneous auditory monitoring of output), which they practice extensively from childhood throughout their entire careers.

Arguably the greatest concert film of all time. Of course, some would argue The Last Waltz or Woodstock or...

It appears to me that you have a very positive view of Trump. 😏

"These findings indicate that a specific brain state of musical creation is formed ... in which [neurons in] the primary visual and motor areas...are recruited to enhance the functional connectivity between the ACC and the default mode network to plan the integration of musical notes with emotion."

"This collection explores the science of learning to move and its impact on cognition, how the neuropsychological aspects of the creative movement process is manifested in the brain, and how creative movement or dance can be harnessed to enhance health, cognitive function, and quality of life."

"...and deactivation of angular gyrus and supramarginal gyrus, brain structures implicated in semantic processing of language... Therefore, we argue that neural regions for syntactic processing are not domain-specific for language but instead may be domain-general for communication."

For drummers: "The experience of groove is a trade-off between stimulus complexity (amount of syncopation) and the ability to maintain a sufficiently stable metre for moving in time with music."

Probably trying to maximize group differences

This hypothesis is supported by the strong association we found between structural differences, musician status, and practice intensity.

Although some of these multiregional differences could be attributable to innate predisposition, [authors] believe they may represent ... adaptations in response to long-term skill acquisition and the repetitive rehearsal of those skills.
