Tone deafness - a right brain problem
PEOPLE who are tone deaf (not your bad shower singers but those
who truly cannot hear or produce musical tones) are actually
processing the sounds differently in their brains, researchers
reported. The researchers said they found the problem in the
right side of the brain. The study, led by Isabelle Peretz of
the University of Montreal, used an EEG to measure brain
activity. For the study, eight tone-deaf adults and 10 others
were connected to an EEG and asked to listen to a series of
musical tones. Half the time, one of the notes was pitched up or
down. The study found that the brain of the tone deaf, or amusic
volunteers did not respond to small changes in pitch that caused
changes among the other volunteers. The researchers said more
study was needed to narrow down where in the brain the problem
was taking place.
