Humans have a metronome-like ability to mark regular time intervals by clapping their hands, rocking, swaying, nodding or tapping their feet that does not seem to be shared by other mammals nor any other members of the animal kingdom. Not only that, but humans have the ability to synchronize their timed movements with each other, with music, or with mechanical devices such as metronomes. Humans are able to dance because of those abilities, but very little has been known about how humans are able to do those things and consequently about how humans are able to dance.
Steven Brown, director of the NeuroArts Lab in the Department of Neuroscience and Behavior at McMaster University in Ontario, Canada, and Lawrence Parsons, a professor in the Department of Psychology at the University of Sheffield in England, published an interesting article entitled "The Neuroscience of Dance" in the July 2008 issue of Scientific American magazine. In that article they report on recent brain-imaging studies that reveal some of the complex neural processing that enables us to dance.
Their first neuroimaging study of dance movement was conducted by means of Positron-Emission Tomography (PET) in conjunction with Michael Martinez of the University of Texas Health Science Center at San Antonio using ten amateur Argentine Tango dancers as subjects. Even though cerebral blood-flow changes in the brains of Argentine Tango dancers were studied, there is no reason to think the results would not be the same for Flamenco Tango dancers or dancers dancing any other type of dance.
I won't summarize more about their research or findings here, because you can read the text of the article on-line at http://www.sciam.com/article.cfm?id=the-neuroscience-of-dance. {NOTE: This article was available on-line without charge when I linked to it, but is no longer available without charge.} However, the printed magazine article is more interesting, because it includes Positron-Emission Tomography images, brain area drawings, and sidebar explanations that are not included in the on-line version.
Scientific American magazine is available at most university libraries and at many major city libraries throughout the world.
