Outline of Final Research Achievements

The aim of this study was to investigate the neurophysiological foundations of musical and cognitive functions in musicians, with a particular focus on their interrelationships. Through a TMS-EEG study, we elucidated the relationship between cognitive function, TMS-elicited alpha band power in the prefrontal cortex, and time spent practicing a musical instrument in groups with and without extensive music learning experience. Further, our MRS study shed light on the association between glutamate concentration in the caudate nucleus and musical rhythm generation capabilities. Additionally, we identified a link between rhythm perception-generation function and mismatch negativity potentials in patients with schizophrenia. These findings contribute to our understanding of the neurocognitive mechanisms underlying musical ability and cognition, offering novel perspectives for future research.

Academic Significance and Societal Importance of the Research Achievements

音楽は太古の昔から世界中に普遍的に存在したが、音楽がヒトの認知機能に与える影響についてはまだ科学的に十分に理解されていない。本研究は、音楽機能と認知機能の関連性やその神経基盤について、現在不足している科学的エビデンスを着実に補った点で意義がある。統合失調症患者の音楽リズム知覚生成機能や認知機能・神経評価指標との関連を明らかにした成果は、精神医学と音楽療法の関係に新たな洞察を与えうる点で学術的意義がある。音楽学習経験と認知機能の関連、前頭前皮質機能と認知機能・楽器練習時間の関連性を明らかにした成果は、音楽が人々の健康と長寿にどのように貢献するかについて、科学的な理解を深めた点で社会的意義がある。
