Alone in a Crowd: Effect of a Nonfunctional Lateral Line on Expression of the Social Hormone Parathyroid Hormone 2
Venuto, Alexandra; Smith, Cameron P.; Cameron-Pack, Marybelle; Erickson, Timothy (2022) -
Arrangement of dermal chromatophore units in a polymorphic species, Ranitomeya imitator
De Araujo Miles, Mallory (East Carolina University, 2021-12-03)In the 1980s, Rainer Schulte became the first to describe a species of poison frog living in the Amazon rainforest: Ranitomeya imitator. Schulte's classification of R. imitator as a single species sparked immediate ... -
DETERMINING THE MEMBRANE TOPOLOGY OF TRANSMEMBRANE O-METHYLTRANSFERASE IN ZEBRAFISH HAIR CELLS USING A SPLIT GFP SYSTEM
Kittle, Brock R. (East Carolina University, 2021-04-23)Mechanosensory hair cells are used by the auditory and vestibular systems to convert mechanical vibrations into electrical signals. Given their specialized function and morphology, hair cells express a unique set of genes ... -
Evaluating the Death and Recovery of Lateral Line Hair Cells Following Repeated Neomycin Treatments
Venuto, Alexandra; Erickson, Timothy (2021-11-04) -
Investigating the roles of E-T coupling and social environment in the stimulus-dependent expression of parathyroid hormone 2.
Smith, Cameron Paul (East Carolina University, 2021-05-28)In larval zebrafish, parathyroid hormone 2 (pth2) codes for a peptide hormone that is expressed exclusively in cells near the ventral part of the posterior tuberculum, an area of the forebrain involved in sensori-motor ... -
The lhfpl5 Ohnologs lhfpl5a and lhfpl5b Are Required for Mechanotransduction in Distinct Populations of Sensory Hair Cells in Zebrafish
Erickson, Timothy; Pacentine, Itallia V; Venuto, Alexandra; Clemens, Rachel; Nicolson, Teresa (2020-01-15)Hair cells sense and transmit auditory, vestibular, and hydrodynamic information by converting mechanical stimuli into electrical signals. This process of mechano-electrical transduction (MET) requires a mechanically ... -
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 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 ...
