“…Digital and physical prototyping tools and open and constrained processes influence brain activity. We found that physical prototyping led to increased brain activation in channels in the right PFC, which is consistent with prior research on creative thinking and divergent cognitive processes (Yi et al, 2022). This may suggest a potential link between the tangible, hands-on nature of physical prototyping and increased creative cognitive processes.…”

This article presents an fNIRS experiment investigating cognitive differences between physical and digital prototyping methods in designers (N=25) engaged in open and constrained design tasks. Initial results suggest that physical prototyping yields increased hemodynamic response (i.e., brain activity) compared to digital design, and that constrained design yields increased hemodynamic response compared to open design, in the prefrontal cortex. Further work will seek to triangulate results by investigating potential correlations to design processes and design outputs.

“…Considering the recent increase in studies identifying new functions associated with the right frontal lobe [37], which include calculation, the signi cance of awake surgery for tumors in this region is even greater. Our two cases may show a need for mapping calculation tasks during awake surgery in the right frontal lobe.…”

Background Many glioma patients struggle to return to work after surgery because of higher brain dysfunction. Although the right frontal lobe has historically been considered functionally silent, reports of performing awake surgery to evaluate higher brain functions in patients with tumors in this area have increased. We present two patients who underwent awake surgery for malignant glioma in the right frontal lobe to preserve emotional recognition and facilitate an early return to work. Case Presentation: Case 1 was a 48-year-old right-handed woman employed as a nursery school teacher and case 2 was a 21-year-old right-handed man employed in sales. Both had contrast-enhancing right frontal lobe tumors exhibiting high signal intensity on fluid attenuated inversion recovery imaging and underwent awake surgery. During the operation, cortical mapping was performed using the Reading the Mind in the Eyes, calculation, and motor tasks. Resection of sites involved in motor and emotional recognition functions was avoided. In case 1, all regions of high signal intensity were completely resected; in case 2, all regions exhibiting enhancement were resected. Both patients were discharged home without neurological deficits and returned to work within 21 days after surgery. Conclusion It may be important to focus not only on overall survival and progression free survival in glioma patients, but also on factors associated with life satisfaction, such as time to return to work after surgery and time until work becomes difficult. Awake surgery aimed at preserving higher brain functions is useful and may also improve life satisfaction.

“…Additionally, prefrontal dysfunction is Rating Scale; HAMA, Hamilton Anxiety Rating Scale; HAMD×HAMA, interaction between HAMD and HAMA a well-known characteristic of depression and suicidal tendencies [23]. The FP2 electrode placement refers to the right prefrontal cortex, a brain region involved in executive functions such as decision-making, working memory, and attention [24]. Structural changes in the prefrontal cortex have been associated with various psychiatric disorders, including depression and anxiety [25].…”

Objective: This study aimed to investigate whether there is a relationship between an individual’s circadian preference and differences in quantitative electroencephalography (QEEG) during the daytime, specifically in patients with mood disorders.Methods: The participants with major depressive disorder, bipolar I disorder, and bipolar II disorder, who had experienced major depressive episodes, were categorized into two or three groups based on their morningness-eveningness preference using the Korean version of the Composite Scale of Morningness (KCSM). The study examined the power of different QEEG bands, such as alpha, beta, theta, delta, and gamma, in the frontal cortex of these patients.Results: The findings indicated that individuals with eveningness preference had significantly lower power in the high gamma band of the right prefrontal cortex compared to those with morningness preference. The average of high gamma powers in the total frontal cortex was also found to be different between the groups. Furthermore, the study revealed a significant association between K-CSM scores and high gamma power, as well as a history of suicide attempts.Conclusion: These results suggest that QEEG may serve as a potential biomarker for circadian preference and suicidality in patients with mood disorders.
