Brain Scans of Rappers and Jazz Musicians Shed Light On Creativity 92

ananyo writes "Rappers making up rhymes on the fly while in a brain scanner have provided an insight into the creative process. Freestyle rapping — in which a performer improvises a song by stringing together unrehearsed lyrics — is a highly prized skill in hip hop. But instead of watching a performance in a club, Siyuan Liu and Allen Braun, neuroscientists at the U.S. National Institute on Deafness and Other Communication Disorders in Bethesda, Maryland, and their colleagues had 12 rappers freestyle in a functional magnetic resonance imaging (fMRI) machine. The artists also recited a set of memorized lyrics chosen by the researchers. By comparing the brain scans from rappers taken during freestyling to those taken during the rote recitation, they were able to see which areas of the brain are used during improvisation. The rappers showed lower activity in part of their frontal lobes called the dorsolateral prefrontal cortex during improvisation, and increased activity in another area, called the medial prefrontal cortex. The areas that were found to be 'deactivated' are associated with regulating other brain functions. The results echo an earlier study of jazz musicians. The findings also suggest an explanation for why new music might seem to the artist to be created of its own accord. With less involvement by the lateral prefrontal regions of the brain, the performance could seem to its creator to have 'occurred outside of conscious awareness,' the authors write in the paper." Bonus points for science rhymes; for anyone who has the time.

      No, they were used to calibrate the zero-point on the scanners.

    I'm sure this thread will have lots of blather about how hip hop lyrics are valid artistic expressions. I used to have the same prejudice, until I started studying epic poetry of Central Asia. Much of the Kyrgyz epic Manas, acclaimed by scholars in the West upon its discovery a century ago, is comparable to most hip hop artists: badly strung together recitations of how the hero has got lots of bling and bitches, and whoops the ass of his enemies.

      I'm sure this thread will have lots of blather about how hip hop lyrics are (not) valid artistic expressions.

      To support your argument that Hip Hop follows a long tradtion:

      LO, praise of the prowess of people-kings
      of spear-armed Danes, in days long sped,
      we have heard, and what honor the athelings won!
      Oft Scyld the Scefing from squadroned foes,
      from many a tribe, the mead-bench tore,
      awing the earls. Since erst he lay
      friendless, a foundling, fate repaid him:
      for he waxed under welkin, in wealth he throve,
      till before him the folk, both far and near,
      who house by the whale-path, heard his mandate,
      gave him gifts: a good king he!

      Beowulf (Prologue) [mcmaster.ca]

      or

      Yo! I know you heard of the Scyldings already
      When battle went down, the kings were deadly, swords steady
      Each one did whatever he said he
      Would do, and to grab onto more glory was ready.
      Scyld started their line, looked mighty fine
      Just a baby found a-bobbin' in a boat
      Grew great so kings gave him silver and gold

      So, the poetry of a violent, war-like culture is similar to rap? Someone should do a study into why that is.

        Except the Kyrgyz were not a violent, war-like culture. At the time that the Manas tradition evolved, the Kyrgyz were a pretty peaceful nomadic pastoral society surrounded by great empires who were changing the borders all around them by force.

          And is the translation any good?

          I speak and read Chinese, with a particular interest in classical characters. I've read, with considerable interest, the Tao te Ching in its near-original form, and also numerous English translations. I'm a martial artist, so such an expounding on "the way" is of great interest. I even suffered through a reading by Ursula Le Guin. Man, was that ever annoying. Then I had a few beers to try to forget. And I like her fiction. And I don't particularly like beer. Anyway...

          In the translations, in an attempt to make the content lyrical in English terms, and sometimes to rhyme, and sometimes to map to a particular agenda, the meaning is badly mangled — to be kind about it. The original can say something entirely mundane, and the translation gets all spiritual and freaky. It's enough to make me turn a little green sometimes.

          I wonder if these Kyrgz translations are more of the same.

          In the case of English and Chinese, the languages don't have anything even remotely resembling a 1:1 map once you get any further into them than "Ni hao", and even then... Someone probably, somewhere, might have told you Ni hao means hello... that's a very common start. What it actually means, though, is "you good" as an implied question that they do NOT expect you to answer... but if you go for "Ni hao ma" that's actually asking "you good?" whereas the first form doesn't indicate a need for an answer (compare to asking someone "how ya doin?", and they start telling you, while you groan to yourself "it was RHETORICAL, please SHUT UP!") It's not hello and it doesn't mean hello, it's just used where we would use hello. Ni hao maps a lot closer to an uninflected (non-questioning) "how ya doin" and ni hao ma to an inflected "how ya DOIN?." But you rarely get taught that, you sort of figure it out later. Well, some do.

          These mapping issues get much stronger as you get into any deeper meanings. In Chinese, that is. So... when I see translations of poetry and particularly when attempts are made to rhyme in another language... I get a little (more) cynical. :) Somehow I doubt that Kyrgyz ramblings make much sense at all in modern English, no matter what you do to 'em. That is to say, if you do enough to get them to make sense, they no longer map back to the original well.

          I can guarantee that's the case for English translations of the Tao te Ching. If you actually want to understand it, you've got a whole culture to learn, and THEN you've got to come to grips with centuries of change.

      I used to think like you until I quit listening to "most hip hop artists" and started paying attention to the ones who stayed in the lab like Niels Bohr, his son Aage, Edward Lorenz and Leo Szilard. The ones that lyrically took rap music and turned the knob, to the right full throttle and added panache.

  • This ties in with the regular hallucinations of fully-arranged original music and songs I experience when I'm waking or falling off to sleep. While my consciousness stays suppressed, the music just flows, and I get a brief insight into how it must feel to be a great improviser. This ties into the concept of The Zone, where thoughts flow organically and associatively, instead of being marshalled by the frontal lobes.

    I start to lose the flow as soon as my consciousness tries to direct things, which is unfo

  • The jazz people have been analyzed, when improvising. Pure creation.

    A rapper, even if the result is terrible, is doing the same thing, except with words.

    I do electronic music production. It's mostly configuration to be honest. But when you find the right sound and the right notes, there is a heavenly moment that is wonderful (atheist speaking here).

  • Could explain the heavy cannabis usage among rappers. Oh yeah, psychedelics don't enhance creativity... wink wink, nudge nudge.
  • Rap = Crap.

  • I'm sure over years, rappers must accumulate word pairings that rhyme, and phrases that slot into rhythms, much the way a jazz player rehearses patterns. In both cases, the fact is that the brain isn't fast enough to both think and execute in real time. Some of the processing has to be done beforehand, and wired in to be executed on command. The trick is to be spontaneous and assemble things in novel ways in spite of the hard wired tendency to arrange them in friendly and familiar ways over and over.
