“…The number of nodes constituting each meta-analytical network was different between networks used in this study. Recently, the influence of network size on single subject identifiability based on NV data has been investigated (Kröll et al, 2023), indicating that the number of nodes in a network are a relevant factor in network-level analyses. The networks that were used in this study are based on meta-analysis and represent various cognitive and psychological domains, so that network size is inherent to each network and cannot be adapted at will.…”

“…Concordantly, a study by Vanderwal and colleagues (2017) showed that movies overall significantly decreased both inter– and intra-subject variability on a whole-brain level compared to RS, thus lending support to the idea that NV might preserve or even enhance individual differences in functional connectivity (Vanderwal, et al 2017). A recent study found that influences of NV on inter– and intra-subject similarity in NFC is dependent on the brain network and stimulus (Kröll et al, 2023), however, not all factors contributing to the effects of movies on inter– and intra-subject similarity of NFC have been investigated. For example, the impact of specific content, such as emotions portrayed in movies, is still unknown.…”

“…With respect to movie fMRI, Vanderwal and colleagues (2017) showed that the effect of movies is differentially distributed across the brain, with lower inter-than intra-subject variability in unimodal regions and higher inter-than intra-subject variability in heteromodal regions. However, a concrete comparison of these variabilities on the level of network functional connectivity (NFC) has rarely been done (but see Kröll et al, 2023). Furthermore, it is yet unclear which features of a movie stimulus influence inter– and intra-subject similarity.…”

Naturalistic paradigms, such as watching movies during functional magnetic resonance imaging (fMRI), are thought to prompt the emotional and cognitive processes typically elicited in real life situations. Therefore, naturalistic viewing (NV) holds great potential for studying individual differences. However, in how far NV elicits similarity within and between subjects on a network level, particularly depending on emotions portrayed in movies, is currently unknown. We used the studyforrest dataset to investigate the inter- and intra-subject similarity in network functional connectivity (NFC) of 14 meta-analytically defined networks across a full narrative, audio-visual movie split into 8 consecutive movie segments. We characterized the movie segments by valence and arousal portrayed within the sequences, before utilizing a linear mixed model to analyze which factors explain inter- and intra-subject similarity. Our results showed that the model best explaining inter-subject similarity comprised network, movie segment, valence and a movie segment by valence interaction. Intra-subject similarity was influenced significantly by the same factors and an additional three-way interaction between movie segment, valence and arousal. Overall, inter- and intra-subject similarity in NFC were sensitive to the ongoing narrative and emotions in the movie. Lowest similarity both within and between subjects was seen in the emotional regulation network and networks associated with long-term memory processing, which might be explained by specific features and content of the movie. We conclude that detailed characterization of movie features is crucial for NV research.

“…These findings suggest that these brain regions may mainly reflect stable personal traits in general processing of movie stimuli. By contrast, in the higher-level and primary sensory regions, the way individuals process stimuli is highly sensitive to the specific content of movie stimuli (Chen et al, 2020; Kröll et al, 2023). Therefore, our results show that brain activity during naturalistic conditions reflect both stable, trait-like characteristics of individuals and state-driven aspects that are influenced by the specific movie stimulus (Geerligs et al, 2015).…”

Understanding individual differences and brain-behaviour relationships is an essential goal of human neuroscience. Recent studies have shown the great potential of naturalistic stimuli, e.g., movie clips, in advancing this pursuit. While the use of naturalistic stimuli attracts increasing interest, the influence of stimulus selection remains largely unclear. In this study, we show that brain activity is generally sensitive to the choice of movie stimuli at both group and individual subject levels. Using sex classification as an example, we demonstrate that brain activity elicited by different stimuli can lead to distinct prediction performance and unique predictive features. The stimuli that yield better classification performance often elicit stronger synchrony of brain activity across all subjects and are mostly derived from Hollywood films with rich social content and cohesive narratives. Our results highlight the importance of stimulus selection and provide practical guidance for choosing appropriate stimuli, opening up new avenues for future studies on individual differences and brain-behaviour relationships.

Keberadaan mirror neuron menyanggupkan manusia memahami kondisi mental individu lainnya melalui simulasi mental terhadap apa yang sedang dirasakan dan dipikirkan orang lain, cara individu mampu memahami kondisi emosi orang lain dan menunjukkan rasa empati terhadap mereka [34].…”

Humans are essentially created as social creatures and need each other to interact with each other. Human life coexists with other humans, so social interaction cannot be avoided. As humans, we must be sensitive and respectful of each other. One of the social interaction capitals is the ability to empathize. Empathy can be defined as when an individual can feel what others feel, and this can be explained from a neuroscience perspective. The mirror neuron is one of the small parts of the brain that has the primary function as a mirror within the individual, in other words it is the center of the process where empathy occurs. The purpose of this study is to investigate the function of mirror neurons that are closely related to human empathy processes and the damage or dysfunction that occurs in it. Through literature studies, it is known that the mirror neurons are located in some parts of brain structures; in the premotor area and the lower parietal cortex. Mirror neurons generally project events around the individuals so the emotions and such behaviors are felt by the individuals. The lack of empathy experienced by some individuals with psychopathy as well as difficulty in understanding situations or responding to social cues in children with Autism Spectrum Disorder (ASD) can be due to the dysfunction in mirror neurons. However, mirror neurons dysfunction still requires further research to be able to understand the role of mirror neurons in various aspects of mental processes and human behavior.
