“…Previous work has shown that narratives elicit correlated neural responses across subjects in regions of the Default Mode Network (DMN), including temporal parietal junction (TPJ), angular gyrus, temporal poles, posterior medial cortex (PMC), and medial prefrontal cortex (mPFC) (Hasson et al, 2008, 2010; Jaaskelainen et al, 2008; Wilson et al, 2008; Lerner et al, 2011; Ben-Yakov et al, 2012; Simony et al, 2016a; Pollick et al, 2018). This shared response is driven by the content and interpretation of the narrative, rather than its form.…”

Humans have a striking ability to infer meaning from even the sparsest and most abstract forms of narratives. At the same time, flexibility in the form of a narrative is matched by inherent ambiguity in its interpretation. How does the brain represent subtle, idiosyncratic differences in the interpretation of abstract and ambiguous narratives? In this fMRI study, subjects were scanned either watching a novel 7-min animation depicting a complex narrative through the movement of geometric shapes, or listening to a narration of the animation's social story. Using an intersubject representational similarity analysis that compared interpretation similarity and neural similarity across subjects, we found that the more similar two people's interpretations of the abstract shapes animation were, the more similar were their neural responses in regions of the default mode network (DMN) and fronto-parietal network. Moreover, these shared responses were modality invariant: the shapes movie and the verbal interpretation of the movie elicited shared responses in linguistic areas and a subset of the DMN when subjects shared interpretations. Together, these results suggest a network of high-level regions that are not only sensitive to subtle individual differences in narrative interpretation during naturalistic conditions, but also resilient to large differences in the modality of the narrative.

“…The posterior cingulate has been identified as a key node in the DMN, and is suggested to act as a cortical hub Leech & Sharp, 2013;Greicius, Krasnow, Reiss, & Menon, 2003) that is involved in multiple functional networks (van den Heuvel & Sporns, 2013). Previous studies have discussed the involvement of hub areas in watching dance (Pollick et al, 2018). Furthermore, recent work has shown engagement of the DMN in social tasks (Mars et al, 2012;Schilbach, Eickhoff, Rotarska-Jagiela, Fink, & Vogeley, 2008) and lower ISC in the DMN in autism while watching complex social interactions (Salmi et al, 2013).…”

“…Moreover, dance has been shown to elicit ISC maps (Pollick et al, 2018;Herbec, et al, 2015;Jola et al, 2013;Reason et al, 2016). In particular, a preliminary study (Pollick, Kim & Jang, 2014) examining typical observers and using 90 s segments of either romantic or classical ballet repertoire found evidence that ISC could be obtained in brain regions associated with action understanding.…”

Evidence regarding whether people diagnosed with Autism Spectrum Disorder (ASD) show differences in processing human movement is mixed, with recent findings being both in support and in contrast. To provide more clarity, this study utilised inter-subject correlation (ISC) analysis to quantify similarities in human movement processing in fMRI responses to a naturalistic movie paradigm portraying ballet dance between adults with and without ASD. Moreover, similarities within each individuals fMRI responses over repeated viewings were quantified to see if responses were stable and if idiosyncratic patterns could be determined. One group difference found was a cluster in the right posterior cingulate showing significantly lower ISC for the ASD group, corresponding to extensive literature showing atypical activity in the Default Mode Network in ASD. Idiosyncratic brain activation patterns were found only for a subset of ASD individuals, opening up the possibility to subtypes and a possible link to severity in symptoms.

“…The 300 only cluster to survive was from the voxel-null model for the contrast T D > ASD and revealed a cluster of 567 mm 3 at right posterior cingulate (peak at Talairach coordinates 4, -42, 25). The posterior cingulate can be considered a hub region, with dense connections to other brain regions (Leech and Sharp, 2013; van den Heuvel and Sporns, 2013) and the involvement of hub areas in watching dance has been discussed in previous examinations of watching dance using ISC (Pollick et al, 2018). One potential basis for the 305 lower ISC in posterior cingulate in the autism group is that the posterior cingulate has been shown to have idiosyncratic resting state functional connectivity in autism (Nunes et al, 2018).…”

Inter-subject correlation (ISC) based analysis is a conceptually simple approach to analyze functional magnetic resonance imaging (fMRI) data acquired under naturalistic stimuli such as a movie. We describe and validate the statistical approaches for comparing ISCs between two groups of subjects implemented in the ISC toolbox, which is an open source software package for ISC-based analysis of fMRI data. The approaches are based on permutation tests. We validated the approaches using five different data sets from the ICBM functional reference battery tasks. First, we created five null datasets (one for each task) by dividing the subjects into two matched groups and assumed that no group difference exists. Second, based on one null dataset, we created datasets with simulated ISC differences of varying size between the two groups. Based on the experiments with these two types of data, we recommend the use of subject-wise permutations, instead of element-wise permutations. The tests based on subject-wise permutations led to correct false positive rates. We observed that the null-distributions should be voxel-specific and not based on pooling all voxels across the brain as is typical in fMRI. This was the case even if studentized permutation tests were used. Additionally, we experimented with an fMRI dataset acquired using a dance movie stimulus for comparison of a group of adult males on the autism spectrum to a matched typically developed group. The experiment confirmed the differences between voxel-based permutation tests and global model based permutation tests.
