近年來，研究人類大腦功能性的反應中最廣為人使用的便是功能性磁振造影(Functional Magnetic Resonance Imaging，fMRI)，在聽覺皮質反應區域上的定位，已經被證明與定義，因此，我們採用音樂認知作為目標。本研究主要著重在音樂節奏上的反應，並以專業音樂家和非專業音樂家作為分組依據。
初步研究結果顯示專業音樂家分組中有三位的反應區在左腦額下回(BA45/BA47)跟語言區有相關性。由於受試者背景不容易嚴格的控制，因此在大腦功能性反應與機制上還需要更進一步的研究。

Recently functional magnetic resonance imaging has become popular in the studies of human brain functions. As the area of auditory cortex has been proven and defined, we consider music cognition as the next step. In this study, we focus on the response of rhythm. Professional musicians and amateurs were involved in our experiments.

Our preliminary result revealed that three of professional musicians have distinguished activation on left cerebrum Inferior Frontal Gyrus BA45/BA47 (language areas). However, since the subjects’ background is difficult to be strictly controlled, further discussion is necessary to define meaning and brain functions of our experiments.
