| Research Abstract |
Teleost fish exhibit sex differences in a variety of behavioral and endocrine patterns. However, virtually nothing is known about what brain mechanisms underlie these sex differences. The present study has revealed that a steroidogenic enzyme and sex steroid receptors are female-specifically or female-preferentially expressed in several regions of the medaka brain, resulting from the action of estrogen derived from the ovary. These systems within the brain may be relevant to sex differences in some behavioral and/or physiological traits.
