Brain And Behavior

Humans are extraordinarily social, and social isolation has profound effects on our behavior, ranging from increased social motivation following short periods of social isolation to increased anti-social behaviors following long-term social isolation. Mice are frequently used as a model to understand how social isolation impacts the brain and behavior. While the effects of chronic social isolation on mouse social behavior have been well studied, much less is known about how acute isolation impacts mouse social behavior and whether these effects vary according to the sex of the mouse and the behavioral context of the social encounter. To address these questions, we characterized the effects of acute (3-day) social isolation on the vocal and non-vocal social behaviors of male and female mice during same-sex and opposite-sex social interactions. Our experiments uncovered pronounced effects of acute isolation on social interactions between female mice, while revealing more subtle effects on the social behaviors of male mice during same-sex and opposite-sex interactions. Our findings advance the study of same-sex interactions between female mice as an attractive paradigm to investigate neural mechanisms through which acute isolation enhances social motivation and promotes social behavior.

Follow Up Study

8 isolate monkeys were compared in a follow-up study to 8 sophisticated controls in brief cross-sectional pairings with 12 stimulus strangers: 4 adults, 4 age-mates, and 4 juveniles. The isolates were characterized by infantile disturbance, less environmental orality, more fear, more aggression, less sex, less play, and bizarre ritualistic movements. 12-mo. isolates were fearful and nonaggressive but threatened many attacks. 6-mo. isolates were fearful and physically aggressive. The 12-mo. isolates demonstrated practically no positive social behavior. Conclusions are: (a) 6 mo. of social isolation during the first year has negative effects on social behavior up to puberty, (b) abnormal aggression appears in 3-yr.-old 6-mo. isolates, and (c) 12 mo. of isolation suppress or delay this aggression.

AbstractA full understanding of a species’ sociality requires knowledge of their specific social motivations. Following social isolation, animals may show general interest in companionship as a buffer for stress or loneliness, but may also be driven to re-establish expectations and dyadic roles with individuals they had been previously separated from. By deconstructing social behavior across experimental manipulations, it may become possible to disentangle these motivational factors. Physical and vocal interactions were recorded from adult female degu dyads during a series of 20 minute reunion sessions across four experiments. Experiments 1 and 2 found that degu interactions increased following isolation, but also increased after dyads were separated without isolation from other conspecifics. Isolation resulted in more early-session interactions, higher allogrooming before rear-sniffing, and a higher ratio of chitter to non-chitter vocalizations. Experiment 3 showed that a non-social, footshock stressor selectively increased early-session interaction, and Experiment 4 revealed high interaction rates between strangers, with more non-chitter vocalizations and late-session rear-sniffing, and reduced pre-rear-sniff allogrooming. A novel, repeated-k-means clustering approach helped to further specify differences in vocalizations between conditions; e.g., “chaff”-type syllables were more common when relationships were new or potentially being renewed. Results suggest that degus are motivated to establish or re-establish expectations with one-another, and these interactions can differ from those associated with the stress of isolation.

As a highly social species, inclusion in social networks and the presence of strong social bonds are critical to our health and well-being. Indeed, impaired social functioning is a component of numerous neuropsychiatric disorders including depression, anxiety, and substance use disorder. During the current COVID-19 pandemic, our social networks are at risk of fracture and many are vulnerable to the negative consequences of social isolation. Importantly, infection itself leads to changes in social behavior as a component of “sickness behavior.” Furthermore, as in the case of COVID-19, males and females often differ in their immunological response to infection, and, therefore, in their susceptibility to negative outcomes. In this review, we discuss the many ways in which infection changes social behavior—sometimes to the benefit of the host, and in some instances for the sake of the pathogen—in species ranging from eusocial insects to humans. We also explore the neuroimmune mechanisms by which these changes in social behavior occur. Finally, we touch upon the ways in which the social environment (group living, social isolation, etc.) shapes the immune system and its ability to respond to challenge. Throughout we emphasize how males and females differ in their response to immune activation, both behaviorally and physiologically.

Global Threat

The current global threat brought on by the Covid-19 pandemic has led to widespread social isolation, posing new challenges in dealing with metal suffering related to social distancing, and in quickly learning new social habits intended to prevent contagion. Neuroscience and psychology agree that dreaming helps people to cope with negative emotions and to learn from experience, but can dreaming effectively reveal mental suffering and changes in social behavior? To address this question, we applied natural language processing tools to study 239 dream reports by 67 individuals, made either before the Covid-19 outbreak or during the months of March and April, 2020, when lockdown was imposed in Brazil following the WHO’s declaration of the pandemic. Pandemic dreams showed a higher proportion of anger and sadness words, and higher average semantic similarities to the terms “contamination” and “cleanness”. These features seem to be associated with mental suffering linked to social isolation, as they explained 40% of the variance in the PANSS negative subscale related to socialization (p = 0.0088). These results corroborate the hypothesis that pandemic dreams reflect mental suffering, fear of contagion, and important changes in daily habits that directly impact socialization.
