  • Title: The neural networks involved in pitch labeling of absolute pitch musicians.
    Author: Wu C, Kirk IJ, Hamm JP, Lim VK.
    Journal: Neuroreport; 2008 May 28; 19(8):851-4. PubMed ID: 18463500.
    Abstract:
    Investigating the neural substrates of auditory processing of absolute pitch musicians has relevance for understanding the capabilities of the human brain for plasticity. Electroencephalography was used to examine the N1 of auditory-evoked potentials from absolute pitch musicians, nonabsolute pitch musicians, and nonmusicians during tone labeling tasks with and without presentation of a reference tone. Source localization using low-resolution electromagnetic tomography revealed that when labeling tones without a reference, absolute pitch musicians generated greater activity than nonabsolute pitch musicians in the left and right hemispheres. This suggests that when required to label tones without an external reference, absolute pitch musicians have the ability to recruit a greater network than nonabsolute pitch musicians or nonmusicians.
