A growing body of evidence suggests that creativity is associated with functional connectivity across widespread neural networks, including regions associated with executive processes and cognitive control, along with regions linked to the default mode network (DMN) of the brain. This study investigated whether a three-week verbal divergent thinking training modulates functional connectivity in networks that have been related to creativity. In a task-based functional imaging study (Fink et al., 2015), the employed creativity training was found to modulate brain activity in regions closely associated with semantic memory demands. Hence, the specific aim of this study was to assess whether the observed task-related brain changes relate to changes in functional connectivity patterns of the brain at rest, as assessed by independent component analysis. The participants were tested at three time points with an inter-test interval of four weeks each, and randomly assigned to two groups which received the verbal creativity training time-delayed. Findings revealed that successful training of verbal creativity was mirrored by functional connectivity changes in the DMN, sensorimotor and auditory network, and the attention network. These rather global changes in resting-state functional connectivity supplement the findings of task-based fMRI, where changes in more task specific brain regions were found.
