Social familiarity affects mating preference among various vertebrates. Here, we show that visual contact of a potential mating partner before mating (visual familiarization) enhances female preference for the familiarized male, but not for an unfamiliarized male, in medaka fish. Terminal-nerve gonadotropin-releasing hormone 3 (TN-GnRH3) neurons, an extrahypothalamic neuromodulatory system, function as a gate for activating mating preferences based on familiarity. Basal levels of TN-GnRH3 neuronal activity suppress female receptivity for any male (default mode). Visual familiarization facilitates TN-GnRH3 neuron activity (preference mode), which correlates with female preference for the familiarized male. GnRH3 peptides, which are synthesized specifically in TN-GnRH3 neurons, are required for the mode-switching via self-facilitation. Our study demonstrates the central neural mechanisms underlying the regulation of medaka female mating preference based on visual social familiarity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Okuyama, Teruhiro -- Yokoi, Saori -- Abe, Hideki -- Isoe, Yasuko -- Suehiro, Yuji -- Imada, Haruka -- Tanaka, Minoru -- Kawasaki, Takashi -- Yuba, Shunsuke -- Taniguchi, Yoshihito -- Kamei, Yasuhiro -- Okubo, Kataaki -- Shimada, Atsuko -- Naruse, Kiyoshi -- Takeda, Hiroyuki -- Oka, Yoshitaka -- Kubo, Takeo -- Takeuchi, Hideaki -- New York, N.Y. -- Science. 2014 Jan 3;343(6166):91-4. doi: 10.1126/science.1244724.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Graduate School of Science, The University of Tokyo, Tokyo 113-0033, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24385628" target="_blank"〉PubMed〈/a〉
