Driving the brain towards creativity and intelligence: A network control theory analysis

High-level cognitive constructs, such as creativity and intelligence, entail complex and multiple processes, including cognitive control processes. Recent neurocognitive research on these constructs highlight the importance of dynamic interaction across neural network systems and the role of cognitive control processes in guiding such a dynamic interaction. How can we quantitatively examine the extent and ways in which cognitive control contributes to creativity anf intelligence? To address this question, we apply a computational network control theory (NCT) approach to structural brain imaging data acquired via diffusion tensor imaging in a large sample of participants, to examine how NCT relates to individual differences in distinct measures of creative ability and intelligence. Recent application of this theory at the neural level is built on a model of brain dynamics, which mathematically models patterns of inter-region activity propagated along the structure of an underlying network. The strength of this approach is its ability to characterize the potential role of each brain region in regulating whole-brain network function based on its anatomical fingerprint and a simplified model of node dynamics. We find that intelligence is related to the ability to “drive” the brain system into easy to reach neural states by the right inferior parietal lobe and lower integration abilities in the left retrosplenial cortex. We also find that creativity is related to the ability to “drive” the brain system into difficult to reach states by the right dorsolateral prefrontal cortex (inferior frontal junction) and higher integration abilities in sensorimotor areas. Furthermore, we found that different facets of creativity—fluency, flexibility, and originality—relate to generally similar but not identical network controllability processes. We relate our findings to general theories on intelligence and creativity.

“…These regions share connections with, and are linked to, language- and executive-related functions providing an adversity-related bridge between the brain, cognitive deficits, behavioral symptoms and persistent offending styles (Anda et al, 2006; Lansing et al, 2014; Piquero, 2001; Raine et al, 2005). The left pars opercularis, supramarginal gyrus, and lingual gyrus have been associated with language-related functions (auditory processing, language comprehension and production, word identification, recognition, and naming), social communication/cognition, and executive functioning (Badre et al, 2010; Frey et al, 2008; Kozlovskiy et al, 2014; Klepousniotou et al, 2013; Mechelli et al, 2000; Piquero, 2001; Raine et al, 2005; Skipper et al, 2007). LCPD boys' neuroanatomical correlations with adversity-related symptoms, coupled with smaller left hippocampal volumes in LCPD boys compared to controls, provide support for both verbal and visual-spatial difficulties reported in delinquent and non-delinquent maltreated populations (Lansing et al, 2014; Mothes et al, 2015; Raine et al, 2005), and suggest that difficulties are most common when there is increased executive demand (e.g., verbal working memory).…”

Delinquent youth have substantial trauma exposure, with life-course persistent delinquents [LCPD] also demonstrating elevated cross-diagnostic psychopathology and cognitive deficits. Because adolescents remain in the midst of brain and neurocognitive development, tailored interventions are key to improving functional outcomes. This structural magnetic resonance imaging study compared neuroanatomical profiles of 23 LCPD and 20 matched control adolescent boys. LCPD youth had smaller overall gray matter, and left hippocampal, volumes alongside less cortical surface area and folding within the left pars opercularis and supramarginal cortex. LCPD youth had more adversity-related exposures, and their higher Cumulative Trauma, Adversity and Grief [C-TAG] symptoms were associated with less surface area and folding in the pars opercularis and lingual gyrus. Neuroanatomical differences between LCPD and control youth overlap with data from both maltreatment and antisocial literatures. The affected left frontal regions also share connections to language- and executive-related functions, aligning well with LCPD youths' cognitive and behavioral difficulties. These data also dovetail with research suggesting the possibility of neurodevelopmental delays or disruptions related to cumulative adversity burden. Thus, concurrent treatment of LCPD youths' C-TAG symptoms and, cognitive deficits with overlapping neuroanatomical bases, may be most effective in improving outcomes and optimizing neurodevelopmental trajectories.

“…In addition, "action syntax," or meaningful structured sequences of actions, may be related to structural processing in both music and language (Harding et al, 2011;Fazio et al, 2009;Fitch & Martins, 2014;Jackendoff, 2009;Sammler, Novembre, Koelsch, & Keller, 2013). Of course, cognitive control processes are not restricted to LIFG; it is clear that both left and right frontal mechanisms are involved in cognitive control (e.g., Aron, 2008;Gläscher et al, 2012), including in the sorts of revision-demanding situations discussed here (e.g., there is bilateral IFG involvement in the processing of lexical ambiguity; Klepousniotou, Gracco, & Pike, 2013). Because musical manipulations often involve bilateral frontal activation (see Figure 6, and Koelsch, 2011, for a review), musical processing may be particularly well suited to investigate the role of right frontal regions in complex cognition.…”

Processing structure in language and music: a case for shared reliance on cognitive control

The relationship between structural processing in music and language has received increasing interest in the last several years, spurred by the influential Shared Syntactic Integration Resource Hypothesis (SSIRH;Patel, 2003). According to this resource-sharing framework, music and language rely on separable syntactic representations but recruit shared cognitive resources to integrate these representations into evolving structures. The SSIRH is supported by findings of interactions between structural manipulations in music and language. However, other recent evidence suggests that such interactions can also arise with non-structural manipulations, and some recent neuroimaging studies report largely non-overlapping neural regions involved in processing musical and linguistic structure. These conflicting results raise the question of exactly what shared (and distinct) resources underlie musical and linguistic structural processing. This paper suggests that one shared resource is prefrontal cortical mechanisms of cognitive control, which are recruited to detect and resolve conflict that occurs when expectations are violated and interpretations must be revised. By this account, musical processing involves not just the incremental processing and integration of musical elements as they occur, but also the incremental generation of musical predictions and expectations, which must sometimes be overridden and revised in light of evolving musical input.
