Summary:
Tone deafness -- or amusia -- can be congenital, present from birth, or acquired following injury to the brain. In a new study, researchers now report the first objective measurement of the brain deficit in congenital amusia.

In an article published online August 29, 2005, in the Annals of Neurology (www.interscience.wiley.com/journal/ana), researchers now report the first objective measurement of the brain deficit in congenital amusia.

Thefindings may have implications both for amusia and for speech learningdisabilities, according to lead study author Isabelle Peretz, Ph.D., ofthe University of Montreal.

Peretz and collaborators at theUniversity of Helsinki assessed brain cell responses to tones acrossdifferent brain areas using electroencephalography (EEG).

Comparedto control subjects, people with congenital amusia show abnormal brainactivity in the right half of the brain, consistent with earlierfindings by Peretz's group and others.

It may be possible tocompensate for amusia by training pitch discrimination abilities."However, it is likely that the intervention will only be effective ina 'plastic' brain, in children. We see no sign of improvement inadults," said Peretz.

Amusic adults show a normal range ofintelligence and have no other brain deficits. They get little payofffrom pitch training and typically find it annoying. Their performanceon tests of pitch may even decrease with continued testing.

Thereis greater hope for children, especially since an understanding ofamusia may have broader implications. Researchers believe thatcongenital amusia has similarities with dyslexia and related disorders.

"Ourfindings should contribute to understanding the origins of learningdisorders – the genetic causes and their neural consequences," saidPeretz.
