Successful Breeding of New Type of Transgenic Killifish Allows Visualization of Genetic Expression of Hormones in Brain

Animals exhibit a range of instincts, including aggression, reproduction, and feeding. All of these instincts are essential for living beings--humans included--to live. It is believed that behavior is controlled by environmental and biogenic factors. However, it remains a mystery as to what exactly these control mechanisms are. The key to solving this mystery very likely lies in the brain, the control center of behavior in vertebrates. But the brain's neural network is extremely complex. Using fish, which display relatively simple brain functions and behavioral patterns among vertebrates, we have been looking into what role special hormone genes that are manifested in the brain play in controlling behavior. We recently succeeded in breeding a new kind of transgenic killifish that allows us to visualize the genetic expression of hormones in the brain. Using these killifish, we can delve deeper into how neurons that manifest special genes function during certain types of behavior in living things.
