Biomedical engineers from George Washington University, Northwestern University, and the University of Arizona have developed a method of observing individual neurons working by inserting a dye and then shining light on the dye, according to a study published in The Proceedings of the National Academy of Sciences and a summary published in Science Daily.  The tiny device uses the light to observe biochemical processes of neurons at work.  It runs on the brain’s electromagnetism and hopefully will help researchers who are searching for ways to help stop neurodegenerative diseases such as Parkinson’s and Alzheimer’s diseases.
