针对用于各类临床人群的即兴音乐疗法的潜在神经动力学的实际研究在很大程度上是缺乏的。本单一案例研究探讨了在一次音乐治疗过程中，一名痴呆患者（PwD）和一名音乐治疗师在音乐特征以及脑内和脑间耦合方面的疗程内差异。
记录了来自一名音乐治疗师和一名痴呆患者（男性，31岁）的双脑电图。从视听数据中提取了音符密度、节奏清晰度和同步性。三名音乐治疗师在两段即兴击鼓演奏中识别出感兴趣和不感兴趣的时刻（MOI/MONI）。对综合耦合指数（反映时间滞后的神经同步性）以及音乐特征在MOI和MONI之间进行了比较。
在MOI期间，2赫兹活动的脑间耦合增强，显示出治疗师神经活动的前置性。在MOI期间，痴呆患者从额叶和中央区域的脑内耦合更强，但治疗师的脑内耦合在MONI期间更强。音乐特征的差异表明，在MOI期间，双方在音乐上的表现彼此更为相似。
神经同步和音乐特征的疗程内差异凸显了音乐疗法的动态性质。
这些研究结果有助于更好地理解大脑中的社会和情感过程以及在现实音乐治疗疗程的特定时刻的（互动性）音乐行为。这可能为这类时刻在关系治疗过程中的作用提供见解。
Real-life research into the underlying neural dynamics of improvisational music therapy, used with various clinical populations, is largely lacking. This single case study explored within-session differences in musical features and in within- and between-brain coupling between a Person with Dementia (PwD) and a music therapist during a music therapy session. Dual-EEG from a music therapist and a PwD (male, 31 years) was recorded. Note density, pulse clarity and synchronicity were extracted from audio-visual data. Three music therapists identified moments of interest and no interest (MOI/MONI) in two drum improvisations. The Integrative Coupling Index, reflecting time-lagged neural synchronization, and musical features were compared between the MOI and MONI. Between-brain coupling of 2 Hz activity was increased during the MOI, showing anteriority of the therapist’s neural activity. Within-brain coupling for the PwD was stronger from frontal and central areas during the MOI, but within-brain coupling for the therapist was stronger during MONI. Differences in musical features indicated that both acted musically more similar to one another during the MOI. Within-session differences in neural synchronization and musical features highlight the dynamic nature of music therapy. The findings contribute to a better understanding of social and affective processes in the brain and (interactive) musical behaviors during specific moments in a real-life music therapy session. This may provide insights into the role of such moments for relational-therapeutic processes.
