“…In the same line, recent evidence suggests that a balanced level between segregation and integration is needed for effective behavior and cognition ( Wang et al. 2021 ; Fransson and Strindberg 2023 ). Importantly, it remains poorly understood how the system-level segregation balance between task-negative networks as the DMN, and attentional networks, relates to complex mental processes in childhood that depend on an adequate attention span such as intelligence.…”

Crystallized abilities are skills used to solve problems based on experience, while fluid abilities are linked to reasoning without prior knowledge. To what extent crystallized and fluid abilities involve dissociated or overlapping neural systems is debatable. Due to often deployed small sample sizes or different study settings in prior work, the neural basis of crystallized and fluid abilities in childhood remains largely unknown. Here we analyzed within and between network connectivity patterns from resting-state functional MRI of 2707 children between 9 and 10 years from the ABCD study. We hypothesized that differences in functional connectivity at the default mode network (DMN), ventral, and dorsal attentional networks (VAN, DAN) explain differences in fluid and crystallized abilities. We found that stronger between-network connectivity of the DMN and VAN, DMN and DAN, and VAN and DAN predicted crystallized abilities. Within-network connectivity of the DAN predicted both crystallized and fluid abilities. Our findings reveal that crystallized abilities rely on the functional coupling between attentional networks and the DMN, whereas fluid abilities are associated with a focal connectivity configuration at the DAN. Our study provides new evidence into the neural basis of child intelligence and calls for future comparative research in adulthood during neuropsychiatric diseases.

Cet article expose la manière dont les sciences des réseaux peuvent contribuer à la compréhension du Trouble de Stress Post-Traumatique (TSPT). Nous soulignons l’intérêt de concevoir le cerveau comme un système complexe et dynamique pour affiner la description et la prédiction des réponses cérébrales après exposition à un évènement traumatique. À partir des modèles de résilience au stress et sous le prisme des sciences des réseaux, nous proposons une ligne temporelle du TSPT, partant des facteurs de résilience intrinsèques au réseau, présents avant l’évènement traumatique, jusqu’à la réponse cérébrale ayant lieu après l’évènement traumatique. Dans ce cadre, il est essentiel de considérer la topologie du cerveau et les dynamiques cérébrales dans des processus permettant d’utiliser ces facteurs de résilience. Ainsi, nous proposons un cadre concret, autorisant la formulation d’hypothèses explicites sur des aspects potentiellement critiques de l’organisation et des dynamiques des réseaux cérébraux impliqués dans le TSPT.
