Graduate school (Masters of Public Health): Heather Torkleson
Our research focus on how central nervous system myelin develops and adapts to the environment. The major questions we are addressing are:
Development. How do oligodendrocytes target their myelin sheaths to only certain subsets of nerve axons, while leaving other axon types unmyelinated? Which genes are required for sheath targeting?
Plasticity. Do experiences or changes to neural activity cause oligodendrocytes to shift myelin onto, away from, or between circuits? Which genes regulate the extent that individual axons are myelinated in an activity-dependent manner?
Evolution. When and how did the oligodendrocyte cell type, myelinating phenotype, and adaptive myelination program first evolve?
Our primary research organism is the embryonic and larval zebrafish, due to its transparency and ease of genetic manipulation.
