Amplitude-frequency tradeoffs in the active sensory and communication signal of a weakly electric fish
Chu, Zhicong (2017-06)Animal communication signals play an important role in behavioral processes to ensure fitness and survivorship of individuals within a species. Weakly electric fish produce communication signals that could be among the ... -
Does Acute Melatonin Supplementation Affect Cerebrovascular Reactivity in Healthy Young Adults?
Mixon, Christopher (2024-05-10)Melatonin receptors have been found in the cerebrovasculature in animal models, and melatonin has been shown to improve systemic vascular control. While there is a correlation between low melatonin production and cardiovascular ... -
Electrophysiological differences between specialized and multifunctional turtle spinal cord neurons involved in scratching and swimming motor patterns
Morris, Madison (2023-08-04)I examined the electrophysiology of both multifunctional and specialized neurons located in the turtle spinal cord, which are activated during swimming, scratching, and/or flexion reflex. My research analyzes these neurons ... -
Electrosensory and Metabolic Responses of Weakly Electric Fish to Changing Water Conductivity
Wiser, Shannon (2022-12-16)South American weakly electric fishes (Gymnotiformes) use self-generated electric fields, known as electric organ discharges (EODs), for sensory processes such as navigation and communication. EOD production incurs significant ... -
Molecular Evolution of a Na, K-ATPase in Weakly Electric Fish
Riedmann, Hiliary (2016-12)African mormyrids and South American gymnotiforms are two independently evolved lineages of weakly electric fish that produce electric organ discharges (EODs) as sensory and communication signals. EOD frequency varies ... -
The Pattern Electroretinogram as an Indirect Measure of Dopaminergic Status in Iron Deficiency
Newbolds, Sarah (2023-08-04)Animal studies have suggested that iron deficiency negatively affects dopamine (DA) synthesis and reuptake, which in turn negatively affects memory and cognition. However, the literature on the possible relationships among ...
