Sex steroid hormones are synthesized from cholesterol and exert pleiotropic effects notably
in the central nervous system. Pioneering studies from Baulieu and colleagues have …

This brief commentary reviews key steps in the history of steroid endocrinology that have
resulted in important conceptual shifts. Our understanding of the “Fast Effects of Steroids” …

Teleost fish form the largest group of vertebrates and show a tremendous variety of adaptive
behaviors, making them critically important for the study of brain evolution and cognition …

Animals constantly integrate external stimuli with their own internal physiological state to
make appropriate behavioural decisions. Little is known, however, about where in the brain …

Goldfish has been used as an unconventional model organism to study a number of
biological processes. For example, goldfish is a well-characterized and widely used model …

Beside their genomic mode of action, estrogens also activate a variety of cellular signaling
pathways through non-genomic mechanisms. Until recently, little was known regarding the …

Although androgens are widely studied in the context of aggression, androgenic influences
on prosocial behaviours have been less explored. We examined testosterone's (T) influence …

Despite sharing much of their genomes, males and females are often highly dimorphic,
reflecting at least in part the resolution of sexual conflict in response to sexually antagonistic …

Estradiol can modulate neural activity and behavior via both genomic and nongenomic
mechanisms. Environmental cues have a major impact on the relative importance of these …

The major classes of chemicals and brain pathways involved in sexual arousal in mammals
are well studied and are thought to be of an ancient, evolutionarily conserved origin. Here …
