Correction: Li et al., Activation of Glycogen Synthase Kinase-3β Is Required for Hyperdopamine and D₂ Receptor-Mediated Inhibition of Synaptic NMDA Receptor Function in the Rat Prefrontal Cortex

In the article “Activation of Glycogen Synthase Kinase-3β Is Required for Hyperdopamine and D₂ Receptor-Mediated Inhibition of Synaptic NMDA Receptor Function in the Rat Prefrontal Cortex” by Yan-Chun Li, Dong Xi, Joy Roman, Yue-Qiao Huang, and Wen-Jun Gao, which appeared on pages 15551–15563 of the December 9, 2009 issue, the authors wish to point out that a single set of data for treatment with 200 μm dopamine (DA, Fig. 1, n = 5) was used in several comparisons (Fig. 2A,B; Fig. 3B,C; and Fig. 4A,B,C,D). The associated statistical tests were not adjusted for multiple comparisons because the comparisons were between individual drugs and 200 μm DA.
