Outline of Final Research Achievements

Medaka females can discriminate between socially-familiarized and unfamiliar males and prefer to mate with the former. Here we showed that GnRH3 neurons have a central role in the mate preference for the familiar males. In addition, we established a gene manipulation technique for site-specific Cre/loxP recombination in the telencephalon and a novel behavioral system to investigate an ability of individual recognition.
