The study of sex differences has produced major insights into the organization of animal
phenotypes and the regulatory mechanisms generating phenotypic variation from similar …

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

In contrast to mammals, teleost fish have a very labile genetic sex determination. Sex
differentiation is influenced by a combination of hormonal, social and environmental factors …

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 …

Seasonal changes in reproductive-related vocal behavior are widespread among fishes.
This review highlights recent studies of the vocal plainfin midshipman fish, Porichthys …

To dissect the molecular and cellular basis of sexual differentiation of the teleost brain,
which maintains marked sexual plasticity throughout life, we examined sex differences in …

Across all major vertebrate groups, androgen receptors (ARs) have been identified in neural
circuits that shape reproductive‐related behaviors, including vocalization. The vocal control …

The brain of teleost fish exhibits a significant degree of sexual plasticity, even in adulthood.
This unique feature is almost certainly attributable to a teleost‐specific sexual differentiation …

Historically, most studies of vertebrate central pattern generators (CPGs) have focused on
mechanisms for locomotion and respiration. Here, we highlight new results for ectothermic …

The ability of steroid hormones to rapidly influence cell physiology through nongenomic
mechanisms raises the possibility that these molecules may play a role in the dynamic …
