Auditory sensory processing is an important element of the neural mechanisms controlling human vocalization. We evaluated which components of Event Related Potentials (ERP) elicited by the unexpected shift of fundamental frequency in a subject's own voice might correlate with his/her ability to process auditory information. A significant negative correlation between the latency of the N1 component of the ERP and the Montreal Battery of Evaluation of Amusia scores for Melodic organization was found. A possible functional role of neuronal activity underling the N1 component in voice control mechanisms is discussed.
听觉感觉处理是控制人类发声的神经机制的重要组成部分。我们评估了由主体自身声音的基频意外变化引起的事件相关电位 (ERP) 的哪些成分可能与他/她处理听觉信息的能力相关。发现 ERP 的 N1 成分潜伏期与旋律组织的蒙特利尔音乐障碍评估量表得分之间存在显著的负相关。讨论了 N1 成分所代表的神经元活动在声音控制机制中的可能功能作用。
