ANDROGEN AND PROGESTERONE RECEPTORS KNOCKOUTS IN ZEBRAFISH AFFECT AGGRESSION AND SOCIAL DOMINANCE
Brown, Julia N (East Carolina University, 2019-05-03)ABSTRACT - There is circumstantial evidence that steroids, such as androgens and progesterone, play roles in aggression and social behaviors in vertebrates. However, the genetic basis for these behaviors needs to be further ... -
Effects of progesterone nuclear receptor on dopaminergic nuclei involved in social aggression in zebrafish (Danio rerio)
Priest, Allison M (East Carolina University, 2021-05-28)Aggression is tightly controlled by hormonal and neural regulation in all social animals. Although extensive effort has been invested in studying the neuroendocrine bases of aggressive behavior, our knowledge of the role ... -
Social Regulation of the Escape and Swim Motor Circuits in Dopamine Receptor Type 1 Mutant Zebrafish (Danio rerio)
Ward, Joseph Carl (East Carolina University, 2019-05-03)Dominance hierarchies are an evolutionary mechanism to ensure the stability of animal groups by enabling the division of resources like food and mates according to social rank. Once dominance is established, the behavior ... -
THE EFFECT OF SOCIAL EXPERIENCE ON BRAIN MORPHOLOGY IN ZEBRAFISH (DANIO RERIO)
Blain, Elena I (East Carolina University, 2021-04-23)Adult male Zebrafish form stable dominance relationships that consist of dominant and subordinate animals. The long-term effects of social dominance on nervous system function remain poorly understood. Here, we investigated ... -
THE EFFECT OF SOCIAL EXPERIENCE ON THE SYNERGISTIC NEUROMODULATION OF MOTOR CIRCUITS
Clements, Katie (East Carolina University, 2022-07-15)Forming social groups is a critical adaptive strategy for the survival of many animal species, where conflict between members can result in dominance relationships. Dominance relationships are often formed through aggressive ... -
The Effect of Visual Queues on Social Status Formation and Mauthner Sensitivity in Zebrafish
Keever, Jared Matthew (East Carolina University, 2017-04-27)Zebrafish of the TLN strain, a genetic variant of the Tüpfel Long-fin (TL) wild-type zebrafish that does not display the trademark striped scale pattern of wild-type zebrafish, but are instead pale, were tested through a ... -
THE ROLE OF THE LATERAL LINE IN EARLY LARVAL ZEBRAFISH AND CONTRIBUTION TO MULTISENSORY BEHAVIORS
Venuto, Alexandra (East Carolina University, 2023-07-21)The lateral line is a hair cell-based sensory system that is important for multisensory behaviors like schooling, rheotaxis, and predator/prey detection in aquatic vertebrates. This dissertation work uses the first genetic ...
