Analyzing Early Embryonic Cell Division Defects in Caenorhabditis Elegans

Krishnakumar, Sheetal (University of Oregon, 2014-06)

Searching for and analyzing novel mutant phenotypes in early cell division of C. elegans allows researcher to infer how the wild-type gene/ protein normally functions after observing defects. To investigate these phenotypes, ...
Establishing Heritability for Value Based Decision Making Qualities in Anandamide treated Caenorhabditis Elegans Natural Isolate Strains

Purcell, Hannah Zhifeng (University of Oregon, 2018-06)

Value-based decision making plays a significant role in the lives and functioning of many organisms and is impacted by drug use often resulting in negative outcomes. Marijuana’s active chemicals mimic the existing ...
Functional Circuitry Controlling the Selection of Behavioral Primitives in Caenorhabditis elegans

Lindsay, Theodore (University of Oregon, 2012)

One central question of neuroscience asks how a neural system can generate the diversity of complex behaviors needed to meet the range of possible demands placed on an organism by an ever changing environment. In many ...
High-Throughput Cloning of Temperature-Sensitive Mutants Affecting Germline Membrane Dynamics in Caenorhabditis elegans

Lowry, Josh (University of Oregon, 2015-08-18)

At the core of Genetics as a field of study is the ability to understand how changes at the genetic level cause changes at the level of the organism. As a part of carrying out these types of investigations, genetic mutations ...
Identifying Genes Required for Cell Division in the Early C. elegans Embryo

Standage, Hayley (University of Oregon, 2013-11)

The oocyte meiotic spindle and the mitotic spindle are necessary to proper cell division and subsequent development of the zygote. The spindle facilitates chromosome segregation to properly distribute genetic information ...
Investigating the mechanisms of DNA repair in C. elegans

Lo, Julia (University of Oregon, 2021)

Meiosis is a specialized cell division that separates homologous chromosomes to generate haploid sperm and egg cells. During meiosis, segregation of homologous chromosomes requires induction and repair of DNA double strand ...
Molecular Mechanisms of Homolog-Independent DNA Repair During C. Elegans Meiosis

Toraason, Erik (University of Oregon, 2022-10-04)

Meiosis is the specialized cell division by which most sexually reproducing organisms generate haploid gametes such as sperm and eggs. Meiotic cells of diploid organisms contain four copies of the genome: two homologous ...
A Novel Neural Network Analysis Method Applied to Biological Neural Networks

Dunn, Nathan A. (2006-08)

This thesis makes two major contributions: it introduces a novel method for analysis of artificial neural networks and provides new models of the nematode Caenorhabditis elegans nervous system. The analysis method extracts ...
Transgenerational Inheritance of Starvation Effects on Lifespan and Reproduction in Caenorhabditis elegans

Rantisi, Juliana Gubreal (University of Oregon, 2018-06)

It is imperative to study the effects of stressors on future generations to understand how we can mitigate negative effects that transcend generations. Transgenerational effects occur when the fitness of successive generations ...
What’s in a Choice: Linking Food Preference to Life History Outcomes in C. elegans

Blue, Ben (University of Oregon, 2015-06)

C. elegans is a bacteriovore capable of consuming a variety of bacterial species. When presented a choice between bacterial foods C. elegans exhibits dietary preferences that generally correlate with the ability to support ...
