“…Cognitive problems in patients with insomnia or sleepdeprived individuals may be associated with low structural connectivity and structural abnormalities in the left thalamuspars triangularis tracts. It has been suggested that the neural networks of the cognitive system relate to decreased functional connectivity between the thalamus and inferior frontal gyrus in right-handed sleep-deprived individuals 15,46 or patients with insomnia. 10,14,18 Sleep-deprived adults showed reduced functional connectivity between the left inferior frontal gyrus and parahippocampal area in MRI scans during a selective attentional task.…”

“…13 Activity in the left pars triangularis of the inferior frontal gyrus decreased during category and letter fluency tests, 14 and the blood oxygen leveldependent signal in the left pars triangularis of the inferior frontal gyrus was more activated following short-term sleep deprivation when divergent thinking ability was needed. 15 A meta-analysis including studies comparing activation from rapid eye movement (REM) or NREM sleep to wakefulness found consistently decreased activation in the inferior frontal gyrus during REM sleep, and in the thalamus during NREM sleep. 16 Given the structural and functional abnormalities in the thalamus and left inferior frontal gyrus found in insomnia, investigating the neural connectivity between these 2 areas in insomnia is of interest.…”

Background: Previous studies have reported functional and structural abnormalities in the thalamus and the pars triangularis of the infer ior frontal gyrus in patients with insomnia disorder. However, no studies have been conducted on the white-matter tracts between these 2 brain regions. We aimed to compare the white-matter integrity and structure of the left thalamus-pars triangularis tracts between patients with insomnia and controls, and to characterize the relationship between white-matter integrity and clinical features in patients with insomnia. Methods: In total, 22 participants with insomnia disorder and 27 controls underwent overnight polysomnography and brain magnetic resonance imaging, and then completed self-report clinical questionnaires and neurocognitive tests for spatial planning. Structural and diffusion measures such as fractional anisotropy, axial diffusivity, radial diffusivity and trace were analyzed in group comparison and correlation analyses. Results: The insomnia group showed significantly lower fractional anisotropy (F = 8.647, p = 0.02) and axial diffusivity (F = 5.895, p = 0.038) in the left thalamus-pars triangularis tracts than controls. In patients with insomnia, fractional anisotropy in the tracts was correlated with the results of the Stockings of Cambridge test (r = 0.451, p = 0.034), and radial diffusivity was correlated with Epworth Sleepiness Scale score (r = 0.437, p = 0.042). Limitations: Limitations included analyses of limited brain regions and the cross-sectional design. Conclusion: The insomnia group showed decreased integrity in the left thalamus-pars triangularis tracts, and integrity was correlated with cognition and daytime sleepiness. These results may imply that insomnia is characterized by disintegration of the white-matter tract between the left thalamus and inferior frontal gyrus.

“…DLPFC activation during creative task performance is thought to reflect the involvement of executive control processes (Beaty et al, 2016; Benedek et al, 2014a; Chen et al, 2015, in press). Another prefrontal region commonly implicated in neuroimaging studies of creative cognition is the left inferior frontal gyrus (IFG; Gonen-Yaacovi et al, 2013; Vartanian et al, 2014). The IFG shows robust activation during cognitive tasks that require controlled memory retrieval, particularly those requiring the selection of a target concept among a set of competing alternatives (Grindrod et al, 2008; Zhang et al, 2004).…”

Functional neuroimaging research has recently revealed brain network interactions during performance on creative thinking tasks—particularly among regions of the default and executive control networks—but the cognitive mechanisms related to these interactions remain poorly understood. Here we test the hypothesis that the executive control network can interact with the default network to inhibit salient conceptual knowledge (i.e., pre-potent responses) elicited from memory during creative idea production. Participants studied common noun-verb pairs and were given a cued-recall test with corrective feedback to strengthen the paired association in memory. They then completed a verb generation task that presented either a previously studied noun (high-constraint) or an unstudied noun (low-constraint), and were asked to “think creatively” while searching for a novel verb to relate to the presented noun. Latent Semantic Analysis of verbal responses showed decreased semantic distance values in the high-constraint (i.e., interference) condition, which corresponded to increased neural activity within regions of the default (posterior cingulate cortex and bilateral angular gyri), salience (right anterior insula), and executive control (left dorsolateral prefrontal cortex) networks. Independent component analysis of intrinsic functional connectivity networks extended this finding by revealing differential interactions among these large-scale networks across the task conditions. The results suggest that interactions between the default and executive control networks underlie response inhibition during constrained idea production, providing insight into specific neurocognitive mechanisms supporting creative cognition.

“…Neuroimaging studies also have been conducted to assess the corresponding cerebral response and their relationship with behavioral changes in previous studies. In these studies, the frontal gyrus and parietal lobe showed more activation changes during the cognitive test, including working memory, verbal learning, thinking fluency, and attention test [12,15,45,46]. Except for these two brain regions, studies, which used resting state fMRI, also showed decreased ALFF in the precuneus, angular gyrus, and thalamus [11,32,43].…”

Objective. To investigate whether and how the working memory impairment induced by sleep deprivation (SD) could be recovered by using repetitive transcranial magnetic stimulation (rTMS), as well as to clarify the corresponding brain activity changes. Methods. Seventeen healthy adults received one session of 5.0 Hz rTMS over the left dorsolateral prefrontal cortex (DLPFC) following 24 hours of SD. Resting state functional magnetic resonance imaging (fMRI) and working memory test were performed during a rested waking period, after SD and rTMS. The amplitude of low-frequency fluctuations (ALFF) was used to detect the spontaneous neural activity changes after both SD and rTMS. The relationship between ALFF and the performance of working memory was also assessed by using correlation analysis. Results. After SD, the participants exhibited lower response accuracies and longer reaction times on the working memory tests of letters and numbers. The decreased response accuracy of numbers was significantly improved after rTMS similarly to the state of the rested waking period after a normal night of sleep. ALFF values decreased from the rested waking period state to the state of SD in the brain regions involving the frontal gyrus, precuneus, angular gyrus, and parietal lobe which showed significantly increased ALFF after rTMS. Furthermore, significantly positive correlations were observed between changes of response accuracy and the changes of ALFF value of the inferior frontal gyrus and supramarginal gyrus. Conclusion. These results indicate that high-frequency rTMS applied over left DLPFC may contribute to the recovery of the impaired working memory after SD by modulating the neural activity of related brain regions.
