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 …

Animals evaluate and respond to their social environment with adaptive decisions.
Revealing the neural mechanisms of such decisions is a major goal in biology. We analyzed …

Unlike that of mammals, the brain of teleost fish exhibits an intense aromatase activity due to
the strong expression of one of two aromatase genes (aromatase A or cyp19a1a and …

Many natural and synthetic compounds present in the environment exert a number of
adverse effects on the exposed organisms, leading to endocrine disruption, for which they …

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

Behavioral neuroendocrinology is an integrative discipline that spans a wide range of taxa
and neural systems, and thus the appropriate designation of homology (sameness) across …

Is the female sex steroid estrogen the key to preserved hearing in the aging human? This
question remains unanswered, but hearing loss is more profound in elderly males than …

The pituitary gland controls many important physiological processes in vertebrates,
including growth, homeostasis, and reproduction. As in mammals, the teleost pituitary …

This review highlights recent studies of the anatomical and functional implications of brain
aromatase (estrogen synthase) expression in two vertebrate lineages, teleost fishes and …
