- W4283831660 abstract "In recent years, exploring the physiological and pathological mechanisms of brain functional integration from the neural network level has become one of the focuses of neuroscience research. Due to the non-stationary and nonlinear characteristics of neural signals, its linear characteristics are not sufficient to fully explain the potential neurophysiological activity mechanism in the implementation of complex brain functions. In order to overcome the limitation that the linear algorithm cannot effectively analyze the nonlinear characteristics of signals, researchers proposed the transfer entropy (TE) algorithm. In recent years, with the introduction of the concept of brain functional network, TE has been continuously optimized as a powerful tool for nonlinear time series multivariate analysis. This paper first introduces the principle of TE algorithm and the research progress of related improved algorithms, discusses and compares their respective characteristics, and then summarizes the application of TE algorithm in the field of electrophysiological signal analysis. Finally, combined with the research progress in recent years, the existing problems of TE are discussed, and the future development direction is prospected.近年来，从神经网络层面探索脑功能整合的相关生理病理机制已经成为神经科学领域研究关注的焦点之一。由于神经信号具有非平稳和非线性的特性，其线性特征不足以充分解释复杂脑功能执行过程中潜在的神经生理活动机制。为克服线性算法无法有效分析信号非线性特征的局限性，研究人员提出了传递熵（TE）算法。近年来，随着脑功能网络概念的引入，TE作为非线性时间序列多元分析的有力工具被不断优化。本文先介绍了TE算法的原理以及相关改进算法的研究进展，探讨比较了它们各自的特点，然后总结了TE算法在电生理信号分析领域的应用。最后，结合近几年的研究进展，探讨了TE目前存在的问题，并展望了其未来的发展方向。." @default.
