Cross-domain analogical reasoning (CAR) is a potent cognitive tool that links seemingly unrelated knowledge domains, fostering creative thinking by identifying similarities across different fields. This study aimed to identify functional connectomes encoding individual variations in CAR abilities and assess their role in creativity. Participants included 69 typical university students who underwent resting-state brain MRI scans and behavioral tests. These tests assessed both CAR and within-domain analogical reasoning (WAR) abilities using verbal analogy tasks in the A:B::C:D format and measured individual creativity levels using the Alternative Uses Test (AUT). We employed a connectome-based predictive modeling (CPM) approach, utilizing the Power264 brain atlas to identify functional connectomes supporting CAR abilities. The CPM analysis indicated that the positive network model could reliably predict individual CAR scores. Functional anatomy and lesion analysis revealed that functional connectivity was broadly distributed across the brain. However, the default mode network, along with specific internetwork connections—such as between the salience and sensory/somatomotor mouth networks, and between the fronto-parietal task control and cingulo-opercular task control networks—showed preferential involvement. Moreover, mediation analysis suggested that CAR mediates the influence of brain functional connectomes on creativity. Our research provides evidence for functional neural markers of CAR and reveals a potential neuropsychological pathway for predicting creativity, whereby brain functional connectomes support creativity through CAR.
Internet addiction symptomatology (IAS) is characterized by persistent and involuntary patterns of compulsive Internet use, leading to significant impairments in both physical and mental well-being. Here, a connectome-based predictive modeling approach was applied to decode IAS from whole-brain resting-state functional connectivity in healthy population. The findings showed that IAS could be predicted by the functional connectivity between prefrontal cortex with the cerebellum and limbic lobe and connections of the occipital lobe with the limbic lobe and insula lobe. The identified edges associated with IAS exhibit generalizability in predicting IAS within an independent sample. Furthermore, we found that the unique contributing network, which predicted IAS in contrast to the prediction networks of alcohol use disorder symptomatology (the range of symptoms and behaviors associated with alcohol use disorder), prominently comprised connections involving the occipital lobe and other lobes. The current data-driven approach provides the first evidence of the predictive brain features of IAS based on the organization of intrinsic brain networks, thus advancing our understanding of the neurobiological basis of Internet addiction disorder (IAD) susceptibility, and may have implications for the timely intervention of people potentially at risk of IAD.

Basolateral Amygdala Functional Connectivity in Alexithymia: Linking Interoceptive Sensibility and Cognitive EmpathyNeuroscienceVol. 539PreviewInteroception is the perception of the internal body state (Craig, 2002, 2003). It is considered to play a fundamental role in emotional processing and self-awareness (Tsakiris and Critchley, 2016), and individuals with high interoception can detect and identify their emotional states with sharp insight (Critchley et al., 2004; Herbert et al., 2011). The literature supports the theory that interoception has a wide range of impacts on emotion, behaviours, and mental health (Tsakiris and Critchley, 2016; Harrison et al., 2021; Quigley et al., 2021).

Creativity is typically operationalized as divergent thinking (DT) ability, a form of higher-order cognition which relies on memory, attention, and other component processes. Despite recent advances, creativity neuroscience lacks a unified framework to model its complexity across neural, genetic, and cognitive scales. Using task-based fMRI from two independent samples and MVPA, we identified a neural pattern that predicts DT, validated through cognitive decoding, genetic data, and large-scale resting-state fMRI. Our findings reveal that DT neural patterns span brain regions associated with diverse cognitive functions, with positive weights in the default mode and frontoparietal control networks and negative weights in the visual network. The high correlation with the primary gradient of functional connectivity suggests that DT involves extensive integration from concrete sensory information to abstract, higher-level cognition, distinguishing it from other advanced cognitive functions. Moreover, neurobiological analyses show that the DT pattern is positively correlated with dopamine-related neurotransmitters and genes influencing neurotransmitter release, advancing the neurobiological understanding of creativity. This study used fMRI and MVPA to identify neural patterns predicting divergent thinking (DT). DT engages the default mode and frontoparietal control networks, opposing the visual network, and is linked to dopamine-related neurotransmitters and genes.
Emotions rely on bodily states, and perceiving the emotions of others depends on awareness of one's own emotional state. However, the intercorrelations among interoception, alexithymia, and empathy are not well understood, and the neural mechanisms behind this connection are also largely unknown. To address these issues, 297 college students participated in this study, completing measures of interoceptive sensibility (IS), empathy and alexithymia and undergoing resting-state fMRI scans. The functional connectivity of the amygdala was analysed to identify the neural substrates of alexithymia, and mediation analyses were conducted to examine the mediation effect of alexithymia and alexithymia-specific amygdala functional connectivity on the relationship between IS and empathy. The results showed that higher levels of IS were associated with increased cognitive empathy through weakened alexithymia. Functional connectivity analysis indicated that right basolateral amygdala (BLA)-left precuneus connectivity was negatively related to alexithymia, while right BLA-left precentral gyrus connectivity was positively related to alexithymia. Furthermore, right BLA-left precuneus connectivity was found to mediate the impact of interoception on cognitive empathy. In conclusion, this study provides valuable insights into the relationships among IS, alexithymia, and empathy. The right BLA-left precuneus connectivity may serve as a shared neural substrate between interoception and cognitive empathy.
Novelty and appropriateness are two fundamental components of creativity. However, the way in which novelty and appropriateness are separated at behavioral and neural levels remains poorly understood. In the present study, we aim to distinguish behavioral and neural bases of novelty and appropriateness of creative idea generation. In alignment with two established theories of creative thinking, which respectively, emphasize semantic association and executive control, behavioral results indicate that novelty relies more on associative abilities, while appropriateness relies more on executive functions. Next, employing a connectome predictive modeling (CPM) approach in resting-state fMRI data, we define two functional network-based models—dominated by interactions within the default network and by interactions within the limbic network—that respectively, predict novelty and appropriateness (i.e., cross-brain prediction). Furthermore, the generalizability and specificity of the two functional connectivity patterns are verified in additional resting-state fMRI and task fMRI. Finally, the two functional connectivity patterns, respectively mediate the relationship between semantic association/executive control and novelty/appropriateness. These findings provide global and predictive distinctions between novelty and appropriateness in creative idea generation.
Creativity is critical to economic growth and societal progress. However, assessing creativity using objective approaches remains a challenge. To address this, we employ three objective indicators based on semantic distance to quantify the originality and appropriateness of creativity by analyzing long texts in a story-writing experiment. Global and local distances were generated separately by computing the mean distance of the whole text and the distance between adjacent sentences, and they were positively correlated with story originality in writing. Global cohesion was positively correlated with story rationality in writing, as generated by computing the semantic coherence between the text and story context. At the behavioral level, three semantic indicators were used to measure originality and appropriateness of creativity and reflected individual differences, including creative achievement and creative personality. At the neural level, global distance was best predicted by the features of the salience and default networks, whereas global cohesion corresponded to the control and salience networks. These findings point to a stable neural basis for semantic indicators and verify the idea of separating different dimensions of creativity. Taken together, our results demonstrate the significance of semantic indicators in assessing creativity and provide insights into analyzing long texts in natural paradigm.
Creativity, the ability to generate original and valuable products, has long been linked to semantic retrieval processes. The associative theory of creativity posits flexible retrieval ability as an important basis for creative idea generation. However, there is insufficient research on how flexible memory retrieval acts on creative activities. This study aimed to capture different dynamic aspects of retrieval processes and examine the behavioral and neural associations between retrieval flexibility and creativity. We developed 5 metrics to quantify retrieval flexibility based on previous studies, which confirmed the important role of creativity. Our findings showed that retrieval flexibility was positively correlated with multiple creativity-related behavior constructs and can promote distinct search patterns in different creative groups. Moreover, high flexibility was associated with the lifetime of a specific brain state during rest, characterized by interactions among large-scale cognitive brain systems. The flexible functional connectivity within and between default mode, executive control, and salience provides further evidence on brain dynamics of creativity. Retrieval flexibility mediated the links between the lifetime of the related brain state and creativity. This new approach is expected to enhance our knowledge of the role of retrieval flexibility in creativity from a dynamic perspective.
BackgroundRumination impedes problem solving and is one of the most important factors in the onset and maintenance of multiple psychiatric disorders. The current study aims to investigate the impact of social rejection on rumination and explore the underlying neural mechanisms involved in this process.MethodsWe utilized psychological questionnaire and resting-state brain imaging data from a sample of 560 individuals. The predictive model for rumination scores was constructed using resting-state functional connectivity data through connectome-based predictive modeling. Additionally, a mediation analysis was conducted to investigate the mediating role of the prediction network in the relationship between social rejection and rumination.ResultsA positive correlation between social rejection and rumination was found. We obtained the prediction model of rumination and found that the strongest contributions came from the intra- and internetwork connectivity within the default mode network (DMN), dorsal attention network (DAN), frontoparietal control network (FPCN), and sensorimotor networks (SMN). Analysis of node strength revealed the significance of the supramarginal gyrus (SMG) and angular gyrus (AG) as key nodes in the prediction model. In addition, mediation analysis showed that the strength of the prediction network mediated the relationship between social rejection and rumination.ConclusionThe findings highlight the crucial role of functional connections among the DMN, DAN, FPCN, and SMN in linking social rejection and rumination, particular in brain regions implicated in social cognition and emotion, namely the SMG and AG regions. These results enhance our understanding of the consequences of social rejection and provide insights for novel intervention strategies targeting rumination.
BACKGROUND:Passive coping style (CS) and perceived stress play significant roles as influencing factors in the development of anxiety. However, the underlying neurobiological mechanism linking passive CS and perceived stress to anxiety susceptibility remains elusive. Thus, we aimed to investigate the relationships among passive CS, brain functional connectivity, perceived stress, and anxiety in young adults.METHODS:Data from the longitudinal Gene-Brain-Behavior Project(GBB) and Southwest University Longitudinal Imaging Multimodal Project(SLIM) were used. We confirmed the relationship among anxiety, passive CS and perceived stress. Then, we investigated the mediated functional connectivity between passive CS and perceived stress, and used these functional connections to predict present anxiety and follow-up anxiety one year later.RESULTS:Anxiety scores were significantly positively correlated with passive CS and perceived stress. At the brain network level, connections within the default mode network (DMN) and between the somatomotor network (SMN) and subcortical network (SUN) mediated the relationship between passive CS and perceived stress. Furthermore, present anxiety and follow-up anxiety one year later could be predicted by these mediated functional connections. Nodes with greater predictive contribution were mainly located in the left anterior cingulate gyrus (ACC), left inferior parietal gyrus (IPG), right superior frontal gyrus (SFG), and left middle frontal gyrus (MFG), mainly distributed on the DMN.CONCLUSION:These findings demonstrated that the mediated neurobiological mechanisms between passive CS and perceived stress could be used to predict present and future anxiety, which enhance understanding of the neurobiological basis of anxiety susceptibility in this passive CS and perceived stress and may have implications for early preventing and intervening mental disorders.
Openness to experience and divergent thinking are considered to be critical in real-life creative achievement. However, there is still a lack of neural evidence to explain how creative achievement is related to openness to experience and divergent thinking. Here, a structural equation model and resting-state functional connectivity were used to investigate their relationships in college students. The structural equation model results repeatedly showed that openness to experience and divergent thinking are positively associated with creative achievement, and the resting-state functional connectivity results showed that openness to experience and divergent thinking were both correlated with the attention network and default mode network. However, openness to experience was also correlated with the primary sensorimotor network and frontoparietal control network. Mediation models further corroborated this result. Collectively, these findings support previous works and further indicate that different neural bases may underlie the associations of creative achievement with openness to experience and divergent thinking.
