All animals evaluate the salience of external stimuli and integrate them with internal
physiological information into adaptive behavior. Natural and sexual selection impinge on …

Based on a wide variety of data, it is now clear that birds and teleost (bony) fish possess a
core “social behavior network” within the basal forebrain and midbrain that is homologous to …

Social organisation in animals takes many forms. It includes assemblages of territorial
animals, dominance hierarchies and social groups, among other things. The basic tenet that …

A major challenge in biology is to understand the genetic basis of adaptation. One
compelling idea is that groups of tightly linked genes (ie," supergenes"[1, 2]) facilitate …

The neuropeptide arginine vasotocin (AVT; non-mammals) and its mammalian homologue,
arginine vasopressin (AVP) influence a variety of sex-typical and species-specific behaviors …

Neuroactive steroids synthesized in neuronal tissue, referred to as neurosteroids, are
implicated in proliferation, differentiation, activity and survival of nerve cells. Neurosteroids …

Vasopressin modulates many social and nonsocial behaviors, including emotionality. We
have previously reported that male mice with a null mutation in the V1a receptor (V1aR) …

The neuropeptides arginine vasopressin (AVP) and oxytocin (OXT) are acknowledged as
important modulators of diverse social behaviours. Here we discuss recent studies using …

Arginine vasopressin (AVP) and related peptides affect social behaviors in numerous
species, but AVP influences on human social functions have not yet been established. Here …

Comparative studies over the past year have revealed two new insights into the role of
neuropeptides in the evolution of social behaviors. First, across vertebrate taxa, certain …
