Central to the process of efficient response selection, the integration of perception and action remains a primary focus in neuroscience. The current study sets out to examine the roles of theta, alpha and beta frequency band activity in perception-action binding processes, as well as the corresponding directed connectivity patterns between the associated neuroanatomical structures. To this end, electroencephalography (EEG) data are collected from N = 43 healthy participants performing a classic prime-probe experimental paradigm which are subsequently subjected to EEG-beamforming methods as well as Non-linear Causal Relationship Estimation by Artificial Neural Network in order to identify linear and non-linear connectivity patterns. The results highlight the integral role of the alpha frequency band in the management of perception-action associations, particularly in the maintenance of these associations over time. In contrast, theta band activity appears to be crucial for the organization of sequential information but does not sustain the continuity of perception-action associations across time.
在高效反应选择过程中，感知与行动的整合仍是神经科学的主要研究重点。当前的研究旨在探讨θ波、α波和β波段活动在感知 - 行动绑定过程中的作用，以及相关神经解剖结构之间相应的定向连接模式。为此，从N = 43名健康参与者中收集脑电图（EEG）数据，他们执行经典的启动 - 探测实验范式，随后对这些数据进行EEG波束形成方法以及人工神经网络的非线性因果关系估计，以识别线性和非线性连接模式。结果突出了α波段在感知 - 行动关联管理中的不可或缺作用，特别是在随着时间维持这些关联方面。相比之下，θ波段活动似乎对序列信息的组织至关重要，但无法维持感知 - 行动关联随时间的连续性。
