In the article “Quaking Regulates Neurofascin 155 Expression for Myelin and Axoglial Junction Maintenance” by Lama Darbelli, Gillian Vogel, Guillermina Almazan, and Stéphane Richard, which appeared on pages 4106–4120 of the April 6, 2016 issue, an incorrect image of a peripheral nerve, which could represent a cranial nerve like oculomotorius or trochlearis, was inadvertently shown. (Fig. 3C). The correct image should be as shown below. We have recalculated the g-ratio for optic nerve QKIFL/FL;− (Fig. 3G) and updated the figure (same axon count was used, n = 108).
