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

Tremendous progress has been made in our understanding of the ultimate and proximate
mechanisms underlying social behavior, yet an integrative evolutionary analysis of its …

Abstract Arginine-vasotocin (AVT)/arginine vasopressin (AVP) are members of the
AVP/oxytocin (OT) superfamily of peptides that are involved in the regulation of social …

This series of volumes represents a comprehensive and integrated treatment of reproduction
in vertebrates from fishes of all sorts through mammals. It is designed to provide a readable …

Male sexual behavior comprises a complex pattern of genital and somatomotor responses,
elicited, directed, and maintained by external and internal signals. It includes copulation as …

Recent research has analyzed how individual characteristics, like the exposure to different
hormones and symmetry, affect decision-making and strategic behaviour. The present article …

Although behavior may often be a fairly direct target of natural or sexual selection, it cannot
evolve without changes in subordinate traits that cause or permit its expression. In principle …

A sequence of behaviours which we call courtship initiates reproduction in a large number of
species. In vertebrates, as a component of male sexual behaviour courtship is strongly …

Under natural conditions, many aspects of the abiotic and biotic environment vary with time
of day, season or even era, while these conditions are typically kept constant in laboratory …

Elevated plasma corticosterone during stressful events is linked to rapid changes in
behavior in vertebrates and can mediate learning and memory consolidation. We tested the …
