Research Abstract |
We generated GnRH1, GnRH2, and GnRH3 GFP-transgenic medaka to visualize each neuron in a whole brain in vitro preparation. We recorded spontaneous electrical activities and responses to various neurotransmitter/neuromodulator substances and analyzed their physiological functions. We also generated a transgenic medaka for monitoring the release activity of pituitary gonadotropic hormones and analyzed the central mechanisms of hormone release. Our research achievements enabled us to understand the multiple biological functions of GnRH peptidergic neurons that are based on their evolutionary history.
