Dr. Erin Johnson '02 recently received her Ph.D. in Neuroscience from the University of Rochester School of Medicine, and was inducted as an alumni member of Nu Rho Psi.
Ron Saul, "Chronic activation of the substantia nigra nociceptin/orphanin receptor induces motor deficits similar to Parkinson's disease," 2008. Saul, the 2008 winner of the Neuroscience Award, infused a drug into the substantia nigra of rats and measured the resulting motor behaviors, mood disturbances, and cognitive abilities.
Very little is known about the effects of chronic anthropogenic noise on fish physiology. Furthermore, little research has been done on the stress response of fishes to long-term noise exposure. Zebrafish are an appealing model for a noise/stress study because they are hearing specialists and a model organism. In this study, zebrafish (Danio rerio) are exposed to Gaussian white noise (114 db re1uPa) over a one hour period. Zebrafish cortisol levels are tested at 0, 15, 20, 40, and 60 minutes of white noise exposure to determine stress response. Cortisol concentrations over time did not prove significant against each other (ANOVA; p > 0.05).
