In the presence of temporally organized stimuli, there is a tendency to entrain to the beat, even at the neurological level. Previous research has shown that when adults listen to rhythmic stimuli and are asked to imagine the beat, their neural responses are the same as when the beat is physically accented. The current study explores the neural processing of simple beat structures where the beat is physically accented or inferred from a previously presented physically accented beat structure in a passive listening context. We further explore the associations of these neural correlates with behavioral and self-reported measures of musicality. Fifty-seven participants completed a passive listening EEG paradigm, a behavioral rhythm discrimination task, and a self-reported musicality questionnaire. Our findings suggest that when the beat is physically accented, individuals demonstrate distinct neural responses to the beat in the beta (13-23 Hz) and gamma (24-50 Hz) frequency bands. We further find that the neural marker in the beta band is associated with individuals' self-reported musical perceptual abilities. Overall, this study provides insights into the neural correlates of spontaneous beat processing and its connections with musicality.
在时间组织刺激的存在下，即使在神经水平上，也有一种跟随节奏的趋势。先前的研究表明，当成年人听节奏刺激并被要求想象节奏时，他们的神经反应与节奏被物理强调时相同。本研究探讨了简单节奏结构的神经处理，其中节奏被物理强调或从先前呈现的物理强调的节奏结构中推断出来，在被动听的情况下。我们进一步探讨了这些神经相关性与行为和自我报告的音乐性测量之间的关联。57 名参与者完成了被动听 EEG 范式、行为节奏辨别任务和自我报告的音乐性问卷。我们的发现表明，当节奏被物理强调时，个体在β（13-23Hz）和γ（24-50Hz）频段对节奏表现出明显的神经反应。我们进一步发现，β 频段的神经标记与个体自我报告的音乐感知能力有关。总的来说，这项研究提供了对自发节奏处理的神经相关性及其与音乐性的连接的深入了解。
