Stimulating Brain Cells with Light

The work will be conducted on laboratory rats modelling Parkinson’s disease. The transplanted cells will be derived from skin from an adult human and will have been “reprogrammed” as nerve cells. The light-sensitive protein is obtained from a bacterium, which uses light to gain energy.
