Temporal variability in Resting state BOLD (Blood oxygenation level dependant) motor connectivity

The functional connectivity between the left and right motor cortices can be measured with functional magnetic resonance imaging (fMRI) by looking at the correlation between resting-state fluctuations in the blood oxygenation level dependent (BOLD) signal. Recent work has shown that the strength of the correlation varies considerably over the time. In addition connectivity strength varies greatly across different subjects. In this project we examined whether the variation in connectivity across subjects could be explained by variations in the degree of temporal correlation variability.
