Aromatase is the enzyme that catalyzes the conversion of androgens to estrogens. Initial
studies of its enzymatic activity and function took place in an environment focused on …

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 …

Of the many conceptual distinctions present in psychology today, the approach-avoidance
distinction stands out as one of, if not the, most fundamental and basic. The distinction …

Aromatase-expressing neuroendocrine neurons in the vertebrate male brain synthesize
estradiol from circulating testosterone. This locally produced estradiol controls neural circuits …

Sexually dimorphic behaviors, qualitative or quantitative differences in behaviors between
the sexes, result from the activity of a sexually differentiated nervous system. Sensory cues …

The functions of rapid increases in testosterone seem paradoxical because they can occur
in response to different social contexts, such as male–male aggressive encounters and male …

Thyroid hormones (THs) are well-known regulators of development and metabolism in
vertebrates. There is increasing evidence that THs are also involved in gonadal …

Hormones coordinate the co-expression of behavioral, physiological, and morphological
traits, giving rise to correlations among traits and organisms whose parts work well together …

Experience has shown that therapy using music for therapeutic purposes has certain effects
on neuropsychiatric disorders (both functional and organic disorders). However, the …

In 1849, Berthold demonstrated that testicular secretions are necessary for aggressive
behavior in roosters. Since then, research on the neuroendocrinology of aggression has …
