Join us as we review the biology of the brain! Find out how neurons work and how neuronal cells are outnumbered 9 to 1 by the unsung heroes of the brain, the glial cells. We discuss what we know and don't know about neurodegenerative diseases such as ALS, Parkinson's, and Alzheimer's. Be sure to listen to our interview in the second half of the episode with local researcher, Dr. Heather Wilkins who investigates the role of energy metabolism in Alzheimer's disease. Finally, stick around for our science myth busters to find out if you really only use 10% of your brain.
