One approach to characterize integration is in terms of FC, which is usually inferred on the basis of correlations among measurements of neuronal activity of anatomically separated regions. FC, originally defined as the statistical dependencies among remote neurophysiological events in positron emission … See more Based on a literature review within the neuroimaging and signal processing disciplines, a number of measures were identified that capture statistical dependence between two signals. For all subsequent … See more Three experiments were designed to closely assess each of the alternative measures relative to Pearson’s correlation as well as to … See more Neuroimaging data were acquired from recruited participants on 3T GE 750 scanners (GE Healthcare, Waukesha, WI, USA) with an 8-channel head coil.
