Evaluation and Comparison of EEG Traces: Latent Structure in Nonstationary Time Series
脑电轨迹的评价与比较:非平稳时间序列的潜在结构
We explore and illustrate the use of time series decomposition methods for evaluating and comparing latent structure in nonstationary electroencephalographic (EEG) traces obtained from depressed patients during brain seizures induced as part of electroconvulsive therapy (ECT). Analysis of the patterns of change over time in the frequency structure of such EEG data provides insight into the neurophysiological mechanisms of action of this effective but poorly understood…
