In the article “Thalamocortical and Intracortical Inputs Differentiate Layer-Specific Mouse Auditory Corticocollicular Neurons,” by Bernard J. Slater, Stacy K. Sons, Georgiy Yudintsev, Christopher M. Lee, and Daniel A. Llano, there was an error in a virus label in Fig. 6A, which appeared on pages 256–270 of the January 9, 2019, issue. The virus label should read “AAV2-CAMKIIa-hChR2(H134R)-mCherry” instead of “AAV2-CAG-hChR2-H134R-tdTomato.” This correction does not affect the conclusions of the paper. A corrected version of Figure 6A appears below.⇓
