(Neuron 91, 1137–1153; September 7, 2016) In the originally published version of the article and Supplemental Information, the units used for electrical stimulation were “pA,” but should have been “μA.” Additionally, the current number in the legend to Figure 6B was written as 25, but should have been 30. Finally, the authors did not acknowledge Dr. D. Ginty for sharing SplitCre mice. These errors have been corrected both online and in print. The authors regret the error.
