“…Thus, these regions may be associated with the motivational state through these cognitive and neural mechanisms. Furthermore, as we summarized previously, dopaminergic mechanisms have been shown to be associated with CMDT (Takeuchi et al 2013b), and it appears that the globus pallidus plays a key role in mediating this relationship (Takeuchi et al 2015). The association between the motivational state and CMDT detected in this study can be explained by the same mechanism.…”

“…Next, we investigated whether the MD correlates of motivational states that are also associated with other multiple personalities (Takeuchi et al 2015) and are parts of the circuit of the dopaminergic system are specifically associated with motivational states. After correcting for confounding variables and multiple comparisons, the Vigor subscale of POMS was significantly and negatively correlated with MD in the right globus pallidum, right putamen, right caudate body, and right thalamus.…”

“…Subsequently, after identifying the MD correlates of motivational state (see the Results), we employed ROI approaches to determine whether the MD correlates of motivational states that are also associated with other multiple personalities (Takeuchi et al 2015) and are parts of the circuit of the dopaminergic system are specifically associated with the motivational state or more weakly associated with other mood states. These areas included the right globus pallidum, right putamen, right caudate body, and right thalamus.…”

“…Previously, we showed that creativity measured by divergent thinking (defined as the ability to produce a diversity of responses to an open question (Runco and Albert 1985); CMDT) and the personalities associated with CMDT are negatively correlated with MDDS (Takeuchi et al 2015). We suggested that among the complex cognitive factors involved with major personalities, motivation is the key factor linking these CMDT, CMDT-related personalities, and MDDS on the basis of the nature and psychometric properties of these cognitive factors (Takeuchi et al 2015). However, this notion still remains to be certified.…”

Previously, we proposed that the mean diffusivity (MD), a measure of diffusion tensor imaging (DTI) in areas of the dopaminergic system (MDDS), is associated with motivation. In this study, we tested if and how the motivational state is associated with MD in comparison with other mood states. We also tested the associations of these mood states with multiple cognitive functions. We examined these issues in 766 right-handed healthy young adults. We employed analyses of MD and a psychological measure of the profile of mood states (POMS) as well as multiple cognitive functions. We detected associations between the higher Vigor subscale of POMS and lower MD in the right globus pallidum, right putamen to right posterior insula, right caudate body, and right thalamus, and these associations were highly specific to the Vigor subscale. Similarly, the association of the motivational state with creativity measured by divergent thinking (CMDT) was rather specific and prominent compared with that of the other mood states and cognitive functions. In conclusion, when affective states are finely divided, only the motivational state is associated with MD in the areas related to the dopaminergic system, and psychological mechanisms that had been associated with dopaminergic system (CMDT). These results suggest that these mechanisms specifically contribute to the motivational state and not to the other states, such as depression and anxiety.

“…Gender differences in creativity have been extensively explored in behavioral studies whereas it has rarely been the subject of neuroscientific investigations, although some studies have taken gender differences into account as a covariate or interaction factor in interpreting the link between creativity and brain structure or function (e.g., Takeuchi et al, 2012Takeuchi et al, , 2015. To date, only two EEG studies (Fink & Neubauer, 2006;Razumnikova, 2004), one structural neuroimaging study (Ryman et al, 2014), and one functional neuroimaging study (Abraham, Thybusch, Pieritz, & Hermann, 2014) have been published which specifically addressed the question of gender based brain-related differences in creativity.…”

The topic of gender differences in creativity generates substantial scientific and public interest, but also courts considerable controversy. Owing to the heterogeneous nature of the findings associated with this line of research, the general picture often appears puzzling or obscure. The present article presents a selective overview of psychological and neuroscientific literature that has a relevant bearing on the theme of gender and creativity. Topics that are explored include the definition and methods of assessing creativity, a summary of behavioral investigations on gender in relation to creativity, postulations that have been forwarded to understand gender differences in creative achievement, gender-based differences in the structure and function of the brain, gender-related differences in behavioral performance on tasks of normative cognition, and neuroscientific studies of gender and creativity. The final section of the overview presents a detailed discussion of the idea that differences between men and women in creative cognition are best explained with reference to the gender-dependent adopted strategies or cognitive style when faced with generative tasks. Gender and Creativity 3Creativity refers to the singularly complex human ability to produce novel ideas, generate new solutions, and express oneself in a unique manner. Although prominent works of art and astounding scientific discoveries are the customary associations that are readily evoked when we consider the concept of creativity, our capacity to be creative is evident in virtually all aspects of human life when engaged in language and communication, choice and decision making, as well as planning and organization (Mark A. Runco & Pritzker, 2011;Sawyer, 2012). While the potential to be creative exists within each person, there is considerable individual variability in both the type and amount of creative output that is eventually produced over our lifetimes. A substantial proportion of the empirical investigations in creativity are directed at uncovering which variables have a positive or negative impact on creativity. Gender is one factor that has been explored in this regard within psychological research. This paper provides a general overview of psychological and neuroscientific research that has a direct or indirect bearing on the topic of gender and creativity. The first part of this paper is devoted to understanding what is meant by creativity in terms of definition and methods of assessment. This is followed by a summary of behavioral findings on gender-related differences in creative thinking and a discussion of the explanations that have been forwarded to understand such differences. Current knowledge concerning gender-based behavioral and neurobiological differences in other (non-creative) aspects of cognition is then explored. In the final part of the paper, implications of findings from neuroscientific studies of gender differences in creative thinking are discussed.Gender and Creativity 4

The importance of brain connectivity for creativity has been theoretically suggested and empirically demonstrated. Studies have shown sex differences in creativity measured by divergent thinking (CMDT) as well as sex differences in the structural correlates of CMDT. However, the relationships between regional white matter volume (rWMV) and CMDT and associated sex differences have never been directly investigated. In addition, structural studies have shown poor replicability and inaccuracy of multiple comparisons over the whole brain. To address these issues, we used the data from a large sample of healthy young adults (776 males and 560 females; mean age: 20.8 years, SD = 0.8). We investigated the relationship between CMDT and WMV using the newest version of voxel-based morphometry (VBM). We corrected for multiple comparisons over whole brain using the permutation-based method, which is known to be quite accurate and robust. Significant positive correlations between rWMV and CMDT scores were observed in widespread areas below the neocortex specifically in females. These associations with CMDT were not observed in analyses of fractional anisotropy using diffusion tensor imaging. Using rigorous methods, our findings further supported the importance of brain connectivity for creativity as well as its female-specific association.
