1) Microarray screening of Guillain-Barré syndrome sera for antibodies to glycolipid complexes2) What's Trending: video gaming in children 3) Topic of the Month: Neurology Today® paper on mitochondrial replacementThis podcast begins and closes with Dr. Robert Gross, Editor-in-Chief, briefly discussing highlighted articles from the February 21, 2017 issue of Neurology. In the first segment, Dr. Ted Burns talks with Dr. Hugh Willison about his Neurology® Neuroimmunology & Neuroinflammation paper on microarray screening of autoantibodies to glycolipid complexes in Guillain-Barre syndrome. Dr. Ted Burns talks with Dr. Gerard Martínez Vilavella about video gaming in children for our “What's Trending” feature of the week. In the next part of the podcast Dr. Ted Burns focuses his interview with Dr. Shoukhrat Mitalipov on mitochondrial replacement for genetic diseases.
