Michael J. Prerau, Ritchie E. Brown, Matt T. Bianchi, Jeffrey M. Ellenbogen, Patrick L. Purdon

An Evaluation of Autoregressive Spectral Estimation Model Order for Brain-Computer Interface Applications

Dean J. Krusienski, Dennis J. McFarland, Jonathan R. Wolpaw
2006 2006 International Conference of the IEEE Engineering in Medicine and Biology Society  
Autoregressive (AR) spectral estimation is a popular method for modeling the electroencephalogram (EEG), and therefore the frequency domain EEG phenomena that are used for control of a brain-computer interface  ...  The present study confirms this by evaluating the EEG spectra of data obtained during control of SMR-BCI using different AR model orders and model evaluation criteria.  ...  However, for SMR-BCI applications, the EEG is actively modulated and the dynamics are likely atypical of the EEG examined in the previous studies.  ...

Applications of EEG Neuroimaging Data: Event-related Potentials, Spectral Power, and Multiscale Entropy

Jennifer J. Heisz, Anthony R. McIntosh
2013 Journal of Visualized Experiments  
MSE may be particularly informative of neural network dynamics because it shows timescale dependence and sensitivity to linear and nonlinear dynamics in the data.  ...  However, it is becoming clear that brain signal variability conveys meaningful functional information about neural network dynamics.  ...  The interpretation of results from more traditional applications of neuroimaging data, such as ERP and spectral power, are augmented by measures of complexity like MSE; MSE provides a way to capture the  ...
