Research Interests: My research has focused on the anatomical correlates of information processing in the olfactory system. My colleague, Karen Wolfe, and I are using immunoelectron microscopy and light microscopy to make a comparative study of the expression of glutamate signaling molecules, such as NMDA receptors and glutamate uptake proteins, in the olfactory bulbs of mice and dogs. I have also developed a culture system of olfactory epithelium and olfactory bulb tissues that responds to airborne odorants. My colleagues and I hope to use the culture system to study signaling and signal regulation in olfactory receptor neurons and olfactory bulb neurons. On a different topic, I am studying whether web-based technology contributes positively to student performance in the gross anatomy laboratory.
Teaching Responsibilities: Dr. Josephson is the course coordinator and lectures in Veterinary Neuroanatomy for the Veterinary Neurosciences course for first year veterinary students. She also teaches a graduate level neuroanatomy course
