"This article has been withdrawn by the authors. The authors were recently made aware of issues in Figs. 1A and 2A. In Fig. 1A, the actERK2 panel was manipulated inappropriately, and the GST panel was duplicated in Fig. 1C as the GST panel. In Fig. 2A, the P-Elk panels for ERK2 were duplicated, and the right actERK2 panel for RSK was duplicated in the right actERK2 panel for cFOS. Because the original data are no longer available, in the interest of maintaining accuracy in the published scientific literature, the authors wish to withdraw this article. However, the authors have full confidence in the findings and conclusions of this paper and have replicated the findings in subsequent work."
