Summary: Although aggression is more common in males, females also exhibit aggressive behaviors, especially in certain ecological contexts. This study aims to assess sex differences in aggression and characterize the neuronal activation patterns of the social-decision making network (SDMN) in response to same-sex aggression in zebrafish. The results suggest that both sexes have similar motivation for aggression, but females show shorter conflict resolution and a preference for antiparallel displays instead of overt aggression. Although there are no sex differences in neuronal activation in specific brain areas, agonistic interactions increase neuronal activity in most brain areas in both sexes. Network centrality analysis reveals shared and sex-specific hubs in the SDMN for each social condition. In summary, this study provides insights into the sex differences in agonistic behavior and the neural architecture of intrasexual aggression in zebrafish.

Summary: Individuals in positions of power often struggle with decision-making, as power can either activate approach-related tendencies or lead to avoidant decision-making. This study explores the activation of avoidance-related tendencies in response to elevated power by conducting a scenario-based decision-making test with members of the US Armed Forces. The results show that individuals with higher power found decisions more difficult and were more likely to make avoidant choices, especially in domain-specific decisions. These findings contribute to our understanding of power dynamics and decision-making in uncertain situations.

Summary: A bargaining game is used to develop a feedback mechanism for dynamic social networks group decision making (SN-GDM). The trust relationships between experts are updated based on their consensus state after each round of interaction. A maximum entropy model is established to determine the comprehensive weight of each expert, considering both their influence and social relationships. The proposed feedback mechanism driven by trust relationship aims to promote consensus in SN-GDM by reflecting the interaction behaviors between inconsistent and trusted experts.

Summary: In almost any species, the survival and reproduction of individuals depend on interactions with both conspecifics and heterospecifics. The distinction between intra- and interspecific interactions is largely artificial and may hinder the integration of historically developed concepts. Both types of interactions, with conspecifics and heterospecifics, may have evolutionary consequences.

Summary: Research indicates that cells born in the adult zebrafish brain are sensitive to social stimuli and may play a role in regulating social behavior. This suggests that adult neurogenesis in fish may contribute to behavioral plasticity, with cells being able to respond to external cues and potentially drive changes in behavior.

Summary: Sociality relies on motivational and cognitive components that may have evolved independently, or may have been linked by phenotypic correlations driven by a shared selective pressure. The study of zebrafish behavior suggests the existence of general-domain motivational and cognitive behavioral modules that have been co-opted for the social domain.

Summary: Individuals in a population display different responses to stressful situations. Resilience, which is the ability to recover efficiently, can be a stable and heritable trait that is determined and exhibited early in life. Resilient individuals show a unique stress-induced transcriptional response, and mutations in resilience-associated genes can impact resilience. Transcriptome analysis reveals that resilient individuals downregulate multiple factors of the innate immune complement cascade in response to stress. The complement pathway plays a negative role in determining resilience, while neuropeptides have a positive role.

Summary: The fitness benefits of social life depend on the ability to affiliate with others and form groups, on dominance hierarchies within groups, and on cognitive capacities for recognition, learning, and information transfer. The evolution of these traits is linked with that of neuroendocrine mechanisms, but the causal relationship between the two is still understudied. The use of zebrafish as a model organism has greatly contributed to understanding these aspects. This review highlights the involvement of motivation, cognition, neuroplasticity, and the role of oxytocin-vasopressin neuroendocrine system, reward-pathway monoamine signaling, sex-hormones, and stress physiology in social decision-making.

Summary: Our study shows that the mechanisms of emotional contagion are evolutionarily conserved in zebrafish, and oxytocin plays a role in regulating social fear contagion. Through experiments using oxytocin and oxytocin receptor mutants, we found that oxytocin is both necessary and sufficient for observer zebrafish to imitate the distressed behavior of conspecific demonstrators. The brain regions associated with emotional contagion in zebrafish are homologous to those involved in the same process in rodents, and they receive direct projections from oxytocinergic neurons located in the pre-optic area. Overall, our results support the evolutionary conserved role of oxytocin as a key regulator of basic empathic behaviors across vertebrates.

Summary: The study found that deficiency of Gpr124, Reck, or Wnt7aa genes in zebrafish leads to severe impairment of BBB angiogenesis, but has no apparent effect on the formation of fenestrated capillaries in the CPs, CVOs, and retinal choroid. In addition, the expression and intercellular interaction of Vegfc/d and Vegfa play a crucial role in region-specific fenestrated capillary formation.
