(Neuron 95, 1420–1432; September 13, 2017) In the original article, there was an error in the reported percentage and number of A24b/M2 axons with activity onsets that precede running onset. The percentage of A24b/M2 axons with significant running onset responses that precede running onset is 30% (508 of 1,675). All analysis based on these numbers and Figure S2, which shows the same data, were correct. This error does not affect any of the conclusions of the study. In addition, there was an error in the methods in the description of the timing of the injection of the ibotenic acid for the chronic lesions of A24b. Ibotenic acid was injected 24 hr prior to the imaging experiments. The authors regret these errors and any confusion that may have arisen as a result of them. These errors have now been corrected in the article online.
