Summary of "Exploring directed functional connectivity based on electroencephalography source signals using a global cortex factor-based multivariate autoregressive model."

Partial directed coherence (PDC) computed from multivariate autoregressive (MVAR) model coefficient is increasingly being used to study directed functional connectivity between brain regions in the frequency domain based on electroencephalography (EEG) source signals. However, directly fitting MVAR model to the high-dimensional source signals is difficult. Besides, although PDC measurement often shows good results for simulated data, it is not clear to what extent the results for real data are physiologically plausible.

Process of classifying cells of the immune system based on structural and functional differences. The process is commonly used to analyze and sort T-lymphocytes into subsets based on CD antigens by the technique of flow cytometry.

The measurement of magnetic fields over the head generated by electric currents in the brain. As in any electrical conductor, electric fields in the brain are accompanied by orthogonal magnetic fields. The measurement of these fields provides information about the localization of brain activity which is complementary to that provided by ELECTROENCEPHALOGRAPHY. Magnetoencephalography may be used alone or together with electroencephalography, for measurement of spontaneous or evoked activity, and for research or clinical purposes.

The use of technology-based interventions to improve functional capacities rather than to treat disease.
