“…Phase-to-amplitude coupling appears to serve a crucial role in the coordination of processes that take place in remote neuronal populations, each operating at different characteristic frequencies [60]. In the present data, CFC PAC was the predominant mode of fronto-temporal neuronal interactions undergoing significant development throughout late childhood and into early adulthood, consistent with their proposed crucial role for information encoding, inhibition, and hierarchical organization of cortical systems [15].…”

Intrinsic functional connectivity networks derived from different neuroimaging methods and connectivity estimators have revealed robust developmental trends linked to behavioural and cognitive maturation. The present study employed a dynamic functional connectivity approach to determine dominant intrinsic coupling modes in resting-state neuromagnetic data from 178 healthy participants aged 8–60 years. Results revealed significant developmental trends in three types of dominant intra- and inter-hemispheric neuronal population interactions (amplitude envelope, phase coupling, and phase-amplitude synchronization) involving frontal, temporal, and parieto-occipital regions. Multi-class support vector machines achieved 89% correct classification of participants according to their chronological age using dynamic functional connectivity indices. Moreover, systematic temporal variability in functional connectivity profiles, which was used to empirically derive a composite flexibility index, displayed an inverse U-shaped curve among healthy participants. Lower flexibility values were found among age-matched children with reading disability and adults who had suffered mild traumatic brain injury. The importance of these results for normal and abnormal brain development are discussed in light of the recently proposed role of cross-frequency interactions in the fine-grained coordination of neuronal population activity.

“…In addition, the power differences in the left frontotemporal cortex appeared primarily in bands with frequencies lower than 20 Hz. This finding is consistent with prior research [25,45,49] because it indicates that visual association in the LC designers resulting from realist art stimulation might be involved in episodic encoding and retrieval, particularly when theta-delta coherence is activated.…”

This study aimed to examine the brain activations of designers during visual association and identify the differences in brain activations caused by distinct visual stimulus types among designers with different creativity levels. Twenty-one professional production designers were recruited and divided into three groups. The top third and bottom third of the participants (7 for each) were divided into high creativity (HC) and low creativity (LC) groups for neural comparison analyses. The derived results are outlined as follows: (i) The brain activations of the production designers notably increased in the prefrontal and parietal regions during visual association; (ii) the spectral power of most HC designers was lower than that of the LC designers; (iii) realist art stimulation evoked strong activation in the anterior ventral regions, whereas abstract art stimulation primarily activated the posterior regions; (iv) the differences in brain activations between the HC and LC designers resulting from realist art stimulation were generally larger than were those resulting from abstract art stimulation; and (v) the brain activations of the HC designers resulting from abstract art stimulation were stronger than were those resulting from realist art stimulation, whereas an opposite trend was observed in the LC designers. Few studies to date have empirically explored the relationship between the creativity levels of designers and their visual association. Enhancing the creative performance of designers should feature among the primary goals of the design industry and design education. This study elucidates a novel approach in this critical research area, although further studies are necessary.

“…For example, at age 3, many children are unable to comprehend the rules of simple laboratory cognitive tasks, but by age 5 most children are proficient at these same tasks (Carlson, ). This developmental pattern makes preschool an important time to investigate prefrontal activity during cognitive tasks, as variability in brain function can inform task performance in both adults (e.g., Baldassarre et al, ) and children (Blankenship & Bell, ; Wolfe & Bell, ). Evidence of the development that occurs during preschool is seen in the specific increases in medial prefrontal EEG power from baseline to working memory tasks that occurs in 4‐year‐olds, while a less localized cortical power increase with task performance is seen during a working memory task in infancy (Bell & Wolfe, ).…”

Previous studies provide conflicting results regarding the relation between future thinking and executive functioning during early childhood. Furthermore, little is known of the neural mechanisms involved in future thinking during early childhood. We examined the moderating role of frontal electroencephalogram (EEG) activity on the relation between executive functioning and semantic future thinking performance in a sample of 4-year-old children. Our results suggest that frontal EEG moderates the relation between executive functioning and semantic future thinking performance, but only for medium to high levels of frontal EEG power values. These results provide emerging evidence regarding the role of both executive functioning and frontal brain electrical activity on semantic future thinking in 4-year-olds.
