Two Yale biomedical scientists have received $125,000 from the Michael J. Fox Foundation to research Parkinson’s disease. Mark Saltzman, a professor of biomedical engineering, and Michael Levene, an assistant professor of biomedical engineering, will use the grant to create new ways of visualizing how molecules move in the brains of living animals. The imaging techniques they devise will allow scientists to see how the drugs that treat Parkinson’s disease move to targeted areas of the brain under different conditions. In the last 15 years, though studies have explained the movement patterns of some molecules in the brain, no overarching framework about how drugs move in the brain has been developed. The technology Levene and Saltzman develop will fill that gap, correlating local brain structure with molecular movement.
