Nerve fibers that link perception and motor regions of the brain are disconnected in tone-deaf people, according to new research in the August 19 issue of The Journal of Neuroscience. Experts estimate that at least 10 percent of the population may be tone deaf - unable to sing in tune. The new finding identifies a particular brain circuit that appears to be absent in these individuals.
