The individuals often show consolation to distressed companions or show aggression to the intruders. The circuit mechanisms underlying switching between consolation and aggression remain unclear. In the present study, using male mandarin voles, we identified that two distinct subtypes of oxytocin receptor (OXTR) neurons in the medial amygdala (MeA) projecting to the anterior insula (AI) and ventrolateral aspect of ventromedial hypothalamus (VMHvl) response differently to stressed siblings or unfamiliar intruders using c-Fos or calcium recording. Oxytocin release and activities of PVN neurons projecting to MeA increased upon consoling and attacking. OXTR antagonist injection to the MeA reduced consoling and attacking. Apoptosis, optogenetic or pharmacogenetic manipulation of these two populations of neurons altered behavioral responses to these two social stimuli respectively. Here, we show that two subtypes of OXTR neurons in the MeA projecting to the AI or VMHvl causally control consolation or aggression that may underlie switch between consolation and aggression.

Early maternal loss can have lasting detrimental effects on primate social development. While many rehabilitation settings provide enriching environments to buffer against such effects in orphans, previous research indicates that young bonobo () orphans exhibit striking deficiencies in socio-emotional competence compared to their mother-reared peers. However, such studies are generally cross-sectional, without accounting for changes across the lifespan.

Importance: Cannabis is commonly used by pregnant patients for alleviation of pregnancy-associated symptoms. Multiple national medical associations have recommended against prenatal cannabis use, yet misinformation regarding its safety and efficacy remains prevalent in public discourse. Effective and evidence-based patient counseling on prenatal cannabis use requires a thorough understanding of the existing data on fetal neurodevelopment.

This review delves into the remarkable career and scientific contributions of Frans de Waal, a renowned figure in the field of ethology, primatology with important implications for the field of social neurosciences. Rooted in the Dutch tradition of ethology, influenced by luminaries like Niko Tinbergen and Jan Van Hooff, De Waal's career began with groundbreaking research on chimpanzees, which questioned long-held beliefs about dominance and aggression in animal behavior. His work, epitomized in his influential books, such as "Chimpanzee Politics", "The ape and the sushi master", "The age of empathy", not only revolutionized scientific thinking but also ignited discussions about empathy, morality, and complex cognitive functions in animals.

Introduction: Empathy is the ability of an individual to present and respond to the emotions of others and is thought to originate from parental behavior. Testosterone could promote aggression and inhibit biparental behavior and vasopressin (AVP) could promote aggression. Given levels of aggression and parental care are closely associated with levels of empathy, we hypothesized that testosterone may influence empathetic behavior via the AVP system.
