Abstract

Here, Freeman Neurodynamics is explored to introduce the reader to the challenges of analyzing electrocorticogram or electroencephalogram signals to make sense of two things: (a) how the brain participates in the creation of knowledge and meaning and (b) how to differentiate between cognitive states or modalities in brain dynamics. The first (a) is addressed via a Hilbert transform-based methodology and the second (b) via a Fourier transform methodology. These methodologies, it seems to us, conform with the systems' neuroscience views, models, and signal analysis methods that Walter J. Freeman III used and left for us as his legacy.

摘要

在此，我们探讨弗里曼神经动力学，旨在向读者介绍分析皮质电图或脑电图信号时所面临的挑战，以便理解两件事：（a）大脑如何参与知识和意义的创造；（b）如何区分大脑动力学中的认知状态或模式。第一个问题（a）通过基于希尔伯特变换的方法解决，第二个问题（b）通过傅里叶变换方法解决。在我们看来，这些方法与沃尔特·J·弗里曼三世所采用并留传给我们的系统神经科学观点、模型及信号分析方法相符。
