MUNICH, GERMANY--Current methods of studying nerve cells affected by Alzheimer's diseaseare limited to post-mortem animal models and complicated methods. A new approach, developed at the Center for Neurodegenerative Disease at Ludwig-Maximilians-Universitaet(LMU) has enabled the first directly observed imaging of neuron death in a living organism. The approach, which involves a laser microscope and fluorescent protein, promises to aid development of therapies.
