In this paper, a generalized synchronization-based metric is described to assess functional connectivity in human brain. The metric is a generalized synchronization measure that considers both the amplitude and phase coupling between pairs of fMRI series. This method differs from the correlation measures used in the literature, as it is more sensitive to nonlinear coupling phenomena between time series and it is more robust against the physiological noise.

Abstract
In this paper, a generalized synchronization-based metric is described to assess functional connectivity in human brain. The metric is a generalized synchronization measure that considers both the amplitude and phase coupling between pairs of fMRI series. This method differs from the correlation measures used in the literature, as it is more sensitive to nonlinear coupling phenomena between time series and it is more robust against the physiological noise.File in questo prodotto:
