Social interactions are essential for mammalian life and are regulated by evolutionary
conserved neuronal mechanisms. An individual's internal state, experiences, and the nature …

Individuals occupying dominant and subordinate positions in social hierarchies exhibit
divergent behaviours, physiology and neural functioning. Dominant animals express higher …

In contrast to male rats, aggression in virgin female rats has been rarely studied. Here, we
established a rat model of enhanced aggression in females using a combination of social …

Across species, animals organize into social dominance hierarchies that serve to decrease
aggression and facilitate survival of the group. Neuroscientists have adopted several model …

Social hierarchies are ubiquitous features of virtually all animal groups. The varying social
ranks of members within these groups have profound effects on both physical and emotional …

Aggressive behavior is thought to have evolved as a strategy for gaining access to
resources such as territory, food, and potential mates. Across species, secondary sexual …

Dominance behaviours have been collected for many groups of animals since 1922 and
serve as a foundation for research on social behaviour and social structure. Despite a …

The process of dog domestication likely involved at least two functional stages. The initial
stage occurred when subpopulations of wolves became synanthropes, benefiting from life …

Olfactory dysfunction is manifested in a wide range of neurological and psychiatric diseases,
and often emerges prior to the onset of more classical symptoms and signs. From a …

Dominance status in hamsters is driven by interactions between arginine-vasopressin V1a,
oxytocin (OT), and serotonin 1A (5-HT1A) receptors. Activation of V1a and OT receptors in …
