Increased hierarchical influence of executive control and attention networks in the creative brain: A dependency network analysis

Abstract

Although numerous studies have primarily associated creativity with spontaneous thought and its corresponding neural networks, effective creativity entails much more than uninhibited ideation. It requires the capacity to filter out irrelevant information, maintain optimal attentional tuning, and strategically regulate and refine innovative outputs. We argue that a robust and adaptive executive control network (ECN), operating in concert with attentional networks, is essential for creativity. Accordingly, we hypothesized that high-creative individuals would exhibit enhanced top-down modulation from both the ECN and attention networks onto other brain networks. To test this hypothesis, we employed resting-state fMRI and Dependency Network Analysis (D_EPNA) to examine differences in hierarchical influence patterns across multiple brain regions and networks between individuals with high and low creative abilities. Our analyses revealed that high-creative individuals, relative to their low-creative counterpart, exhibited increased influence of specific brain regions on inter-regional functional connectivity across multiple brain regions. These regions demonstrating augmented influence were predominantly localized within the ECN and ventral attention network (VAN), specifically the bilateral inferior frontal gyrus (IFG), bilateral inferior frontal sulcus (IFS), and right middle frontal gyrus (MFG). Moreover, high-creative individuals displayed significantly greater influence of the ECN and the dorsal attention network (DAN) on other large-scale brain networks. These findings suggest top-down cognitive and attentional control may be crucial in facilitating creativity.
