Erratum: “This Week in the Journal”

In “This Week in the Journal”, which appeared on page 577 of the January 23, 2019 issue, a sentence in NMDA Receptors in Amacrine Cells of the Rod Pathway appeared incorrectly. In the last paragraph, the third sentence should instead read: “Activation of GluN2A-containing NMDARs in A17 amacrines, in contrast, likely inhibits further glutamate release from rod bipolar cells.” The article has been corrected online.
