Following the publication of this article the authors noted an error in Fig. 5. The units of blood concentration for ketamine and norketamine should be ng/mL, as per the assay details in Materials and methods section, and not nM/ml as presented in the figure. A revised Fig. 5 is in the correction article. The authors apologize for any inconvenience caused.
