Profiling The Action Of Acetylcholine In The Drosophila Melanogaster Larval Model: Heart, Behavior, And The Development And Maintenance Of Sensorimotor Circuits, Cole A. Malloy
Theses and Dissertations--Biology
Understanding the role of various chemical messengers in altering behaviors and physiological processes is a common goal for scientists across multiple disciplines. The main focus of this dissertation is on characterizing the action of an important neurotransmitter, acetylcholine (ACh), modulating larval Drosophila melanogaster neural circuits and heart. In this dissertation, I provide important insights into the mechanisms by which ACh influences the formation and performance of select neural circuits, while also revealing significant details regarding its role in additional physiological functions, including cardiac pace making. In Chapter 1, I provide a general overview of ACh action in mammals and flies …
Behavioral Gait Change Characterization And Detection Using Precision Dairy Monitoring Technologies, Barbara Wadsworth Jones
Behavioral Gait Change Characterization And Detection Using Precision Dairy Monitoring Technologies, Barbara Wadsworth Jones
Theses and Dissertations--Animal and Food Sciences
Lameness is a painful disorder that decreases performance and is highly recognized as one of the most important health and welfare concerns for dairy cattle. Visual gait scoring is the most common way to detect gait change in dairy cattle. However, this is not only subjective, but is also time consuming and costly. A need to remove the subjective assessment of human observation exists. Therefore, automatic gait change detection for continuous monitoring by precision dairy monitoring technologies may be beneficial. The first objective of this research was to characterize behavior and production variables as cow gait changed to evaluate potential …
