“…The two networks form an immature twofold attention system that matures with the growing ability of the top-down attention system to counteract the bottom-up system. Our hypothesis is further supported by a recent study by Suo et al(Suo et al 2021), underpinning the stable and reliable anatomical connections of the DAN and the VAN via functional connectors, demonstrating that the functional interaction of the VAN and the DAN is supported by a solid anatomical structure.The mediation analysis of the VAN's inference over the DAN, mediated by the GA found that VAN's connectivity signi cantly modify the transmittance of change of the DAN's connectivity assumed form…”

The Salience Network (SN), Ventral Attention Network (VAN), Dorsal Attention Network (DAN) and Default Mode Network (DMN) have shown significant interactions and overlapping functions in bottom-up and top-down mechanisms of attention. In the present study we tested if the SN, VAN, DAN and DMN connectivity can infer the gestational age (GA) at birth in a study group of 88 healthy neonates with GA at birth ranging from 28 to 40 weeks. We also ascertained whether the connectivity within each of the SN, VAN, DAN and DMN is able to infer the average functional connectivity of the others. The ability to infer GA at birth or another network's connectivity was evaluated using a multi-variate data-driven framework. A mediation analysis was performed in order to estimate the transmittance of change of a network’s functional connectivity (FC) over another mediated by the GA.The VAN, DAN and the DMN infer the GA at birth (p<0.05). The SN, DMN and VAN were able to infer the average connectivity over the other networks (p<0.05). Mediation analysis between VAN’s and DAN’s inference on GA found reciprocal transmittance of change of VAN’s and DAN’s connectivity (p<0.05). Our findings suggest that the VAN has a prominent role in the bottom-up salience detection in early infancy and that the role of the VAN and the SN may overlap in the bottom-up control of attention.

“…MFG, STG, and insula are part of the ventral attention network which is involved in reorienting attention to salient stimuli ( Suo et al, 2021 ). Referring to the longitudinal ASL-based CBF study in breast cancer patients, Chen et al (2017) found significantly increased CBF in the superior frontal gyrus, inferior frontal gyrus, inferior parietal gyrus, and temporal gyrus in post-chemotherapy breast cancer patients.…”

Purpose: This study was performed to investigate the regional cerebral blood flow (CBF) and CBF connectivity in the chemotherapy-induced cognitive impairment of patients with lung cancer by using arterial spin labeling.Methods: Pseudocontinuous arterial spin labeling perfusion magnetic resonance imaging and neuropsychological tests were performed for 21 patients with non-small cell lung cancer who had received chemotherapy CT (+) and 25 non-small cell lung cancer patients who need chemotherapy but did not yet received CT (-). The CT (+) group previously received platinum-based therapy for 3 months to 6 months (the time from their first chemotherapy to the MRI scan). Group comparisons were performed in the regional normalized CBF and CBF connectivity, and the relationship between the regional normalized CBF and cognitive impairment were detected.Results: The CT (+) group exhibited higher CBF in the left insula, right caudate, right superior occipital gyrus, left superior temporal gyrus (STG), and right middle frontal gyrus (MFG). MoCA scores as well as the memory scores were negatively correlated with the increased CBF in the right MFG (r = −0.492, p = 0.023; r = −0.497, p = 0.022). Alterations in the CBF connectivity were detected only in the CT (+) group between the following: right MFG and the right precentral gyrus; the right caudate and the right lingual gyrus; right caudate and right precuneus; left STG and the bilateral MFG; and the left STG and the right middle cingulum.Conclusion: These findings indicated that chemotherapy is associated with abnormalities in the CBF and connectivity alterations, which may contribute to the cognitive impairment in patients with lung cancer.

“…Clarifying these issues will help to completely understand the functional roles of the PT and PT branches. Third, although we only used 50 subjects in HCP, our previous research has demonstrated the stability in HCP subjects ( Suo et al, 2021 ). Finally, our comparison of the four diffusion models is mainly focused on demonstrating the performance of PT and PT branches rather than evaluating their computing time and other parameters.…”

“…Therefore, the map of PT branches is of great significance to clinical diagnosis and prognosis guidance. However, most of the previous studies on the WM fibers of the PT were exclusively based on the DTI diffusion model or one of the other three emerging diffusion models ( Oouchi et al, 2007 ; Wang et al, 2016 ; Schilling et al, 2017 ; Bao et al, 2019 ; Suo et al, 2021 ), and the focus of these studies was primarily limited to the whole fibers of the PT rather than each PT branch. Meanwhile, the anatomical travel of PT is concentrated and the variation is small in comparison with other fiber bundles, which can be used as a typical demonstration reference for evaluating different models.…”

Currently, comparative studies evaluating the quantification accuracy of pyramidal tracts (PT) and PT branches that were tracked based on four mainstream diffusion models are deficient. The present study aims to evaluate four mainstream models using the high-quality Human Connectome Project (HCP) dataset. Diffusion tensor imaging (DTI), diffusion spectral imaging (DSI), generalized Q-space sampling imaging (GQI), and Q-ball imaging (QBI) were used to construct the PT and PT branches in 50 healthy volunteers from the HCP. False and true PT fibers were identified based on anatomic information. One-way repeated measure analysis of variance and post hoc paired-sample t-test were performed to identify the best PT and PT branch quantification model. The number, percentage, and density of true fibers of PT obtained based on GQI and QBI were significantly larger than those based on DTI and DSI (all p < 0.0005, Bonferroni corrected), whereas false fibers yielded the opposite results (all p < 0.0005, Bonferroni corrected). More trunk branches (PTtrunk) were present in the four diffusion models compared with the upper limb (PTUlimb), lower limb (PTLlimb), and cranial (PTcranial) branches. In addition, significantly more true fibers were obtained in PTtrunk, PTUlimb, and PTLlimb based on the GQI and QBI compared with DTI and DSI (all p < 0.0005, Bonferroni corrected). Finally, GQI-based group probabilistic maps showed that the four PT branches exhibited relatively unique spatial distributions. Therefore, the GQI and QBI represent better diffusion models for the PT and PT branches. The group probabilistic maps of PT branches have been shared with the public to facilitate more precise studies on the plasticity of and the damage to the motor pathway.
