Objective: Pansori is a Korean traditional vocal music that has a unique story and melody which converts deep emotion of pain and sorrow into art. The objective of this study is to illustrate the different cortical activation by a Korean traditional opera, Pansori, accoding to its emotional valence using functional MRI (fMRI). Subjects and Methods: Ten right-handed volunteers participated. Their mean age was 25.2. Activation tasks were designed to passively listen a part of Pansori with sad or humorous emotional valence. White noise was introduced for control task. Imaging was conducted on a 1.5T Siemens Vision scanner. Single-shot EPI fMRI scans (TR/TE 3840/40 ms, flip angle 90, FOV 220, 64 x 64 matrix, 6 mm) were acquired in 20 contiguous slices. Imaging data were motion-corrected, coregistered, normalized, and smoothened using SPM-96 software. Results: Bilateral posterior temporal regions were activated in both of Pansori tasks with different hemispheric asymmetry. After subtraction between two tasks, a Pansori with sad emotion showed more activation in the right temporoparietal and orbitofrontal areas, in contrast, the one with humorous emotion showed more activation in the left temporal and prefrontal areas. Conclusion: Different hemispheric and cortical networks may conduct emotional valence carried by Pansori.
