到目前为止，神经生理学研究已经研究了内隐和外显自我相关加工，特别是对自我相关刺激，如自己的脸或名字。本研究将以往的研究扩展到自我相关动作音的内隐加工，并探讨其时空动态。事件相关电位（ERPs）评估时，参与者（N = 12健康受试者）被动地听先前录制的自我和他人相关的手指劈啪声，在一个古怪的范式中被呈现为异常或标准。被动聆听低（500赫兹）和高（1000赫兹）纯音作为额外的控制。对于自我和他人相关的指断声，erp分析显示N2a/MMN和P3的时间窗存在显著差异。随后使用标准低分辨率脑电磁断层扫描（sLORETA）进行的源定位分析显示，在处理自我和他人相关的指断声过程中，不同运动区域的皮质激活增加，如N2a/错配负性（MMN）中的辅助运动区（SMA）以及P3时间窗。相反，在N2a/MMN （ACC/PCC）或P3 （IPL）的时间窗口中，与自我相关处理相关的大脑区域[例如，右侧前/后扣带皮层（ACC/PPC）]以及右侧顶叶下小叶（IPL）显示出激活增加，特别是在处理自我与他人相关的手指劈啪声时。当被动地听低（500赫兹）和高（1000赫兹）纯音时，这些大脑区域都没有表现出增强的激活。综上所述，目前的研究结果表明：(1)在运动相关信息的听觉加工过程中，SMA等运动区域具有特定的作用，无论这些信息是自我相关的还是与他人相关的；(2)在自我相关的运动刺激的内隐加工过程中，ACC/PCC和IPL等神经源的激活；(3)自我和他人相关运动声音在偏离（N2a/MMN - ACC/PCC）和目标检测（P3 - IPL）时的时间激活差异。
So far, neurophysiological studies have investigated implicit and explicit self-related processing particularly for self-related stimuli such as the own face or name. The present study extends previous research to the implicit processing of self-related movement sounds and explores their spatio-temporal dynamics. Event-related potentials (ERPs) were assessed while participants (N = 12 healthy subjects) listened passively to previously recorded self- and other-related finger snapping sounds, presented either as deviants or standards during an oddball paradigm. Passive listening to low (500 Hz) and high (1000 Hz) pure tones served as additional control. For self- vs. other-related finger snapping sounds, analysis of ERPs revealed significant differences in the time windows of the N2a/MMN and P3. An subsequent source localization analysis with standardized low-resolution brain electromagnetic tomography (sLORETA) revealed increased cortical activation in distinct motor areas such as the supplementary motor area (SMA) in the N2a/mismatch negativity (MMN) as well as the P3 time window during processing of self- and other-related finger snapping sounds. In contrast, brain regions associated with self-related processing [e.g., right anterior/posterior cingulate cortex (ACC/PPC)] as well as the right inferior parietal lobule (IPL) showed increased activation particularly during processing of self- vs. other-related finger snapping sounds in the time windows of the N2a/MMN (ACC/PCC) or the P3 (IPL). None of these brain regions showed enhanced activation while listening passively to low (500 Hz) and high (1000 Hz) pure tones. Taken together, the current results indicate (1) a specific role of motor regions such as SMA during auditory processing of movement-related information, regardless of whether this information is self- or other-related, (2) activation of neural sources such as the ACC/PCC and the IPL during implicit processing of self-related movement stimuli, and (3) their differential temporal activation during deviance (N2a/MMN – ACC/PCC) and target detection (P3 – IPL) of self- vs. other-related movement sounds.
