“…Since in the delta and theta range the neural time series of mSPC are statistically more successful in predicting the neural activity in FEF and IFJ than vice versa, we can suggest that SPC drives the spontaneous activity in plPFC during rest. This unidirectional connectivity during rest might reflect similar task-related influences of SPC over plPFC during attention and working memory (Chen et al, 2020; Spadone et al, 2021). Additionally, we observe a frequency-specific direction of interaction in the beta band from parietal areas VIP and 7PL to FEF.…”

“…Therefore, the direction of interaction between SPC and FEF might change depending on the current task demands. While SPC’s highly significant directional influence over plPFC during rest suggests that it might provide some sort of spatial attention signals to FEF, Spadone et al (2021) also showed that the contrast between shift versus stay cues reveals feedback connections from the right FEF to the right SPL. In this respect, the functional hierarchy is not fixed but dynamic.…”

“…Additionally, we observe a frequency-specific direction of interaction in the beta band from parietal areas VIP and 7PL to FEF. A recent study by Spadone et al (2021) similarly indicated that contrasting stay with shift cues reveals a robust direction of information flow from the right ventral IPS to the right dorsal FEF, specifically in the beta band. Since subjects had to fixate during rMEG, the maintenance of attention and the status quo of beta oscillations could have led to the results we observed in the current study.…”

“…While area LIP is also to some degree selective to shape (Sereno & Maunsell, 1998), researchers at large showed its role in spatial attention (Bisley & Goldberg, 2003; Thakral & Slotnick, 2009), the choice of saccade target (Andersen et al, 1990; Barash et al, 1991; Blatt et al, 1990; Kusunoki et al, 2000; Kusunoki & Goldberg, 2003) and the creation of priority maps (Gottlieb, 2007; Ipata et al, 2009; Sprague & Serences, 2013). Finally, it is evident that SPL (areas 7AL and 7PC) takes part in shifting spatial attention (Behrmann et al, 2004; Caspari et al, 2018; Corbetta et al, 1995; Kelley et al, 2008; Molenberghs et al, 2007; Spadone et al, 2021; Vandenberghe et al, 2001; Yantis et al, 2002) and encoding spatial coordinates for planned reach movements (Baldauf et al, 2008; Connolly et al, 2003). Besides, these results match with FEF’s deterministic tractography (Baker et al, 2018).…”

Neuroimaging evidence suggests that the frontal eye field (FEF) and inferior frontal junction (IFJ) govern the encoding of spatial and non-spatial (such as feature- or object-based) representations, respectively, both during visual attention and working memory tasks. However, it is still unclear whether such contrasting functional segregation is also reflected in their underlying functional connectivity patterns. Here, we hypothesized that FEF has predominant functional coupling with spatiotopically organized regions in the dorsal ('where') visual stream, whereas IFJ has predominant functional connectivity with the ventral ('what') visual stream. We applied seed-based functional connectivity analyses to temporally high-resolving resting-state magnetoencephalography (MEG) recordings. We parcellated the brain according to the multimodal Glasser atlas and tested, for various frequency bands, whether the spontaneous activity of each parcel in the ventral and dorsal visual pathway has predominant functional connectivity with FEF or IFJ. The results show that FEF has a robust power correlation with the dorsal visual pathway in beta and gamma bands. In contrast, anterior IFJ (IFJa) has a strong power coupling with the ventral visual stream in delta, beta, and gamma oscillations. Moreover, while FEF is directly phase-coupled with the superior parietal lobe in the beta band, IFJa is directly phase-coupled with the middle and inferior temporal cortex in delta and gamma oscillations. We argue that these intrinsic connectivity fingerprints are congruent with each brain region's function. Therefore, we conclude that FEF and IFJ have dissociable connectivity patterns that fit their respective functional roles in spatial vs. non-spatial top-down attention and working memory control.

“…The superior parietal lobule is an important node of the dorsal attention network, which has similar functions with the intraparietal suleus, the core brain region of the dorsal network, receiving visual information input and participating in the regulation of spatial orientation. Speci cally, the intrapietal sulcus is mainly involved in the endogenous attention shift caused by the change of target features but unchanged spatial position, while the superior parietal lobule is mainly related to the exogenous attention shift caused by the target spatial movement (Molenberghs et al, 2007;Allan et al, 2019;Spadone et al, 2021). The dorsal attention network, also known as the visuospatial attention network, is responsible for the management of spatial attention and visual movement, and participates in the top-down (endogenous) goal-oriented attention orientation (Majerus et al, 2018).…”

Background: Bronchial asthma often causes cognitive impairment, especially attentional deficit, which has a serious impact on children’s learning, but the lack of functional imaging evidence has affected targeted intervention for children.Methods: Thirty-one asthmatic and typically developing children (TDC) were studied by functional magnetic resonance imaging (fMRI). Brain network-based degree centricity and voxel-mirrored homotopic connectivity (VMHC) methods were used.Results: Compared with the TDC group, asthmatic children had lower DC values in the right superior frontal gyrus (after FDR correction, P<0.05). Meanwhile, VMHC values of bilateral superior frontal gyrus and bilateral superior parietal lobule in asthmatic children were lower than those in TDC children (after FDR correction, P<0.05).Conclusions: In this study, impaired superior frontal gyrus and parietal lobe function are associated with attentional deficit in asthmatic children, and these brain regions are key brain regions in attention-related networks.
