Amazing Scientific Discoveries, Part 5

Uncle Jeff, Noted Astrophysicist, writes to say that he went ahead and read the article by Rosenkranz, Williamon, and Rothwell from Journal of Neuroscience 27(19):5200-6, 2007 May 9. He correctly assumed that we'd never get around to reading it (but would say we did) and sent highlights:

p.5200 "Musicians not only have extraordinary motor and sensory skills, but they also have an increased ability to learn new tasks compared with non-musicians."

p.5200 "Similarly, musicians who started musical training before 7 years of age learn a timed motor sequence task much better than musicians who started later or non-musicians."


p.5203 "These features are compatible with the idea that both motorcortical excitability and plasticity are heightened in musicians. Because some of these changes depend on the age at which instrumental playing commenced, we hypothesize that they reflect adaptation to long-term musical practice."

p.5204 "Indeed, changes in gray matter are larger in musicians who started earlier, and they reflect the choice of instrument, consistent with a causal connection between presumed synaptic growth and the duration and pattern of training."


p.5205 "the number of hours of practice is well known to relate to musical skill"

p.5205 "Our experiments do not directly assess whether increased synaptic plasticity is produced by musical training, as a complex motor task and also a multimodal-sensory and emotional experience, or whether it is a genetic trait of successful musicians. However, some parameters correlated significantly with the age at which playing commenced as well as with practice intensity over the last 5 years."


p.5205 "Although this does not completely rule out any preselectional bias, it seems likely that some of the changes of excitability and plasticity are a consequence of long-term musical practice."

p.5205 "These changes may represent a beneficial adaptation in response to long-term musical training"


That's a lot of science for one day, so you're probably glad I skipped the bass player joke.
