“…We evaluated the test–retest reliability of global topological properties (Andellini, Cannata, Gazzellini, Bernardi, & Napolitano, ; Wang et al, ) using the intraclass correlation coefficient (ICC). More specifically, a one‐way ANOVA was used to evaluate the results of both scans in order to calculate the between‐subject mean square ( MS b ) and within‐subject mean square ( MS w ).…”

A major challenge in neuroscience is understanding how brain function emerges from the connectome. Most current methods have focused on quantifying functional connectomes in gray‐matter (GM) signals obtained from functional magnetic resonance imaging (fMRI), while signals from white‐matter (WM) have generally been excluded as noise. In this study, we derived a functional connectome from WM resting‐state blood‐oxygen‐level‐dependent (BOLD)‐fMRI signals from a large cohort (n = 488). The WM functional connectome exhibited weak small‐world topology and nonrandom modularity. We also found a long‐term (i.e., over 10 months) topological reliability, with topological reproducibility within different brain parcellation strategies, spatial distance effect, global and cerebrospinal fluid signals regression or not. Furthermore, the small‐worldness was positively correlated with individuals' intelligence values (r = .17, pcorrected = .0009). The current findings offer initial evidence using WM connectome and present additional measures by which to uncover WM functional information in both healthy individuals and in cases of clinical disease.

“…Interestingly, recent reports suggest that watching a movie during the acquisition of a resting state fMRI scan hardly alters the observable connectivity pattern which makes acquiring such data in children easier. However, this approach is still not in widespread use in the presurgical setting as (1) the direct correspondence between an actually executed task with an observable activation is most important, (2) the test retest reliability is still considered too low for this purpose, and (3) relevant differences in the results from both approaches still exist and need to be better understood . Overall, the use of an active task in a robust block design implementation therefore currently seems preferable in the routine presurgical pediatric setting.…”

“…It should also be remembered that, for younger children in particular, extra padding may be required to ensure optimal head placement in the center of the coil . During noninteractive parts of the scanning session (for example, during the dMRI data acquisition), the child should be entertained by showing (interesting, but not too funny) videos or personally selected audio books or music.…”

The application of both functional MRI and diffusion MR tractography prior to a neurosurgical operation is well established in adults, but less so in children, for several reasons. For this review, we have identified several aspects (task design, subject preparation, actual scanning session, data processing, interpretation of results, and decision‐making) where pediatric peculiarities should be taken into account. Further, we not only systematically identify common issues, but also provide solutions, based on our experience as well as a review of the pertinent literature. The aim is to provide the clinician as well as the imaging scientist with information that helps to plan, conduct, and interpret such a clinically‐indicated exam in a way that maximizes benefit for, and minimizes the burden on the individual child.

“…Related to this, the 387 time-series correlations we report are linked and in some cases mathematically 388 equivalent to intra-class correlations (ICC) (Shrout and Lane, 2012). Finally, it will be 389 interesting to expand the notion of process similarity beyond relationships among 390 corresponding single brain regions: well-controlled movies provide an ideal tool to study 391 similarities of dynamic functional connectivity (Bassett et al, 2011;Simony et al, 392 2016), or similarities of more complex network measures (Andric,393 Small, and Pannunzi et al, 2016;Sizemore, Giusti, Betzel, and Bassett, 394 2016;Wang et al, 2017). Critically, these findings should not be taken to evaluate the 395 reliability of fMRI as a whole.…”

Despite its widespread use in neuroscience, the reliability of fMRI remains insufficiently understood. One powerful way to tap into aspects of fMRI reliability is via the inter-subject correlation (ISC) approach, which exposes different viewers to the same time-locked naturalistic stimulus and assesses the similarity of neural time series. Here we examined the correlations of fMRI time series from 24 participants who watched the same movie clips across three repetitions. This enabled us to examine inter-subject correlations, intra-subject correlations, and correlations between aggregated time series, which we link to the notions of inter-rater reliability, stability, and consistency. In primary visual cortex we found average pairwise inter-subject correlations of about r = 0.3, and intra-subject correlations of similar magnitude. Aggregation across subjects increased inter-subject (inter-group) correlations to r = 0.87, and additional intra-subject averaging before cross-subject aggregation yielded correlations of r = 0.93. Computing the same analyses for parietal (visuospatial network) and cingulate cortices (saliency network) revealed a gradient of decreasing ISC from primary visual to higher visual to post-perceptual regions. These latter regions also benefitted most from the increased reliability due to aggregation. We discuss theoretical and practical implications of this link between neural process similarity and psychometric conceptions of inter-rater reliability, stability, and internal consistency.
