“…The frequency-band specificity of the creativity-related functional connectivities that we observed in this study requires further discussion. Several EEG studies using power spectrum analysis have shown enhancements of neural activity in the alpha band during the performance of creative tasks (Grabner et al, 2007;Fink et al, 2009;Privodnova and Volf, 2016;Privodnova et al, 2017). Using event-related synchronization methods, Grabner et al (2007) and Fink et al (2009) revealed that alphaband activity becomes significantly stronger in the right cerebral cortex during divergent thinking tasks.…”

“…Therefore, the alpha band PLI used in this study is considered as one of the appropriate methods to identify the functional connectivity regarding the creative activity supported by various interactions among brain regions. Furthermore, recent findings on creative ability in the aging process (Roskos-ewoldsen et al, 2008;Leon et al, 2014;Palmiero et al, 2014Palmiero et al, , 2017 have prompted studies on a possible age dependence of the specific neural processes that underlie creative activity (Privodnova and Volf, 2016;Privodnova et al, 2017;Privodnova, 2018). In particular, Privodnova and Volf (2016) and Privodnova et al (2017) demonstrated enhancement of task-related alpha-band activity in the parieto-occipital regions in the final stage of a creative task in older participants.…”

Therefore, the present observation of significant higher alpha-band functional connectivity estimated by the phase synchronization in higher-creativity individuals is consistent with these findings and confirms the involvement in creative activity of alpha-band neural activity/functional connectivity.…”

“…Accumulating evidence suggests that high creativity leads to mental well-being in older individuals (Flood and Scharer, 2006;Flood and Phillips, 2007;Roskos-ewoldsen et al, 2008;Leon et al, 2014;Palmiero et al, 2014Palmiero et al, , 2017, which resulted in increased interest in the role of the neural activity underpinning creative functions in the aging process (Ueno et al, 2015;Privodnova and Volf, 2016;Privodnova et al, 2017;Privodnova, 2018;Adnan et al, 2019). Early studies on creativity and aging found an agerelated decline in creative ability (Alpaugh and Birren, 1977;McCrae et al, 1987), while more recent findings suggest the long-term preservation of creative activity by the aging process (Roskos-ewoldsen et al, 2008;Leon et al, 2014;Palmiero et al, 2014Palmiero et al, , 2017.…”

In older participants engaged in creative tasks, Privodnova and Volf (2016) and Privodnova et al (2017) found task-related enhancements of theta activity in anterior brain areas in the initial stage of task performance, and in the final stage, taskrelated enhancement of alpha activity in the parieto-occipital area and reduction of beta activity in posterior areas. An fMRI study on creative activity and aging revealed that during creative tasks, the functional connectivity of the brains of older participants with high creativity increased significantly, including that of the default network (Adnan et al, 2019).…”

Despite growing evidence that high creativity leads to mental well-being in older individuals, the neurophysiological bases of creativity remain elusive. Creativity reportedly involves multiple brain areas and their functional interconnections. In particular, functional magnetic resonance imaging (fMRI) is used to investigate the role of patterns of functional connectivity between the default network and other networks in creative activity. These interactions among networks play the role of integrating various neural processes to support creative activity and involve attention, cognitive control, and memory. The electroencephalogram (EEG) enables researchers to capture a pattern of band-specific functional connectivity, as well as moment-to-moment dynamics of brain activity; this can be accomplished even in the resting-state by exploiting the excellent temporal resolution of the EEG. Furthermore, the recent advent of functional connectivity analysis in EEG studies has focused on the phase-difference variable because of its fine spatio-temporal resolution. Therefore, we hypothesized that the combining method of EEG signals having high-temporal resolution and the phase synchronization analysis having high-spatio-temporal resolutions brings a new insight of functional connectivity regarding high creative activity of older participants. In this study, we examined the resting-state EEG signal in 20 healthy older participants and estimated functional connectivities using the phase lag index (PLI), which evaluates the phase synchronization of EEG signals. Individual creativity was assessed using the S-A creativity test in a separate session before the EEG recording. In the analysis of associations of EEG measures with the S-A test scores, the covariate effect of the intelligence quotient was evaluated. As a result, higher individual S-A scores were significantly associated with higher node degrees, defined as the average PLI of a node (electrode) across all links with the remaining nodes, across all nodes at the alpha band. A conventional power spectrum analysis revealed no significant association with S-A scores in any frequency band. Older participants with high creativity exhibited Nobukawa et al.Phase Synchronization With High Creativity high functional connectivity even in the resting-state, irrespective of intelligence quotient, which supports the theory that creativity entails widespread brain connectivity. Thus, PLIs derived from EEG data may provide new insights into the relationship between functional connectivity and creativity in healthy older people.
