Correction to: Nature Neuroscience https://doi.org/10.1038/s41593-017-0023-y, published online 27 November 2017.

In the version of this article initially published, a sentence in the third paragraph read, “Suppression of natural orexin signaling by orexin receptor antagonism (Fig. 3b–e) led to increased risk-avoidance behaviors.” “Increased” has been changed to “decreased” in this sentence. The error has been corrected in the HTML and PDF versions of the article.
