Unfortunately, after online publication of the article, it has been noticed that there is a typo under the discussion section of the online published article.

Under “Discussion” in para starting “In the parallel study on the generation…” the sentence “Isothermal titration calorimetry showed that ArcNb H11 binds with high affinity (1 nM Kd) and competitively displaces stargazin, an auxiliary subunit of AMPA-type glutamate receptors, which has the highest binding affinity (34.9 nM) of the known Arc NL ligands [33].” should read as “Isothermal titration calorimetry showed that ArcNb H11 binds with high affinity (1 nM Kd) and competitively displaces stargazin, an auxiliary subunit of AMPA-type glutamate receptors, which has the highest binding affinity (34.9 µM) of the known Arc NL ligands [33].” The “µ” symbol wrongly displayed as “n” in the final version of the online publication. This was corrected by publishing this correction article.
