ONLINE COVER Neurons, the cells that degenerate in numerous neurological diseases, among them Parkinson's disease. This issue of Science Translational Medicine features a historical essay about translational medicine pioneer Arvid Carlsson. His discovery of the utility of L-dopa for treatment of Parkinson's disease still forms the basis of treatment today. Improved methods to deliver L-dopa by gene therapy are being explored, as reported in a Research Article by Jarraya et al. and discussed by Björklund et al. in a Perspective.
