Abstract :
[en] Rodent models have been extensively used to study the neural underpinnings of
aggression. Yet, the role of some external factors such as social experiences, or
internal factors such as biological sex, have only recently gained attention. This
chapter discusses how the composition of the social environment and/or the lack
of social contact (social isolation) in different stages of development impact the
display of aggressive behavior in rodents. Additionally, this chapter covers how
biological sex interacts with changes in the composition of the social environment
to affect the neuronal networks of aggression. From a neurobiological point of
view, this chapter focuses particularly on the participation of neuroendocrine
systems such as sex hormones, oxytocin, and vasopressin and on how social
interactions shape brain plasticity within those systems.
