Here the authors show that measures of pupil diameter, which are thought to track levels of LC-NE activity and neural gain, are correlated with the degree to which learning is focused on stimulus dimensions that individual human participants are more predisposed to process. They further show that the pupillary and behavioral variables are correlated with global changes in the strength and clustering of functional connectivity, as brain-wide fluctuations of gain would predict.
