Overview of our Research
We apply a multifaceted approach to better understand how the central nervous system forms during development.
Our primary focus is on oligodendrocyte-axon interactions. The image at left shows a single spinal cord oligodendrocyte forming numerous myelin sheaths.
We apply genetics to learn how myelin sheaths are formed & stabilized. The image at left shows accumulation of axonal vesicles (white) at ensheathment sites (yellow arrowheads). We utilize transgenisis and DNA plasmid injection into fertilized eggs in order to genetically manipulate subsets of neurons or glia.
Use of transgenic zebrafish embryos enables us to test hypotheses both in vitro and in vivo.

The Neural Development Lab is housed within the Department of Biology and College of Science & Engineering at Winona, State University.

Society for Neuroscience
Katrina Pfaffenbach and Taylor Hobbs present their poster "Development of methods to assess exploratory behavior of pre-myelinating oligodendrocytes in vivo" at the Faculty or Undergraduate Neuroscience poster session.
Heather Nelson presents "Axon determination of subtype specific myelin ensheathment and pruning" at the SFN Central and Peripheral Myelinating Cells session.
James Gronseth and John Henke present "Regulation of oligodendrocyte exploratory behavior and sampling of axons by neural activity" at the SFN Central and Peripheral Myelinating Cells" session.
August 2019. Last day of summer research.
James, Katrina, and Taylor put the finishing touches on their summer projects, and look forward to preparing posters for the 2019 Society for Neuroscience conference in Chicago this October.
May 2019. Students Katrina Pfaffenbach, Taylor Hobbs, and James Gronseth started their summer internships in the lab.
May 2019. Welcome Heather Nelson (WSU Cell and Molecular Biology Class of '17). Heather began her position as research analyst in the lab.
April 2019. Emily Menges featured in the Winona Post! Emily, Taryn Mallon, and James Gronseth presented their research in poster format at the Winona Health Research Fair.
April 2019. As we wrap up final data analysis and progress reports for the National MS Society funded project, happy to officially announce that we received 5 years of funding from the National Science Foundation (CAREER) to study mechanisms of adaptive myelination. Honored and excited to continue this project. This would never be possible without the hard work and investment by currrent and former lab members, as well as support from the MS Society, WSU Biology Department, College of Science and Engineering, and WSU Foundation.
Nick accepted admission to the Physician Assistant Program at Augsburg University (starts May '19, Class of 2021)
