In the article "Presynaptic Regulation of Quantal Size by the Vesicular Glutamate Transporter VGLUT1," by Nathan R. Wilson, Jiansheng Kang, Emily V. Hueske, Tony Leung, Helene Varoqui, Jonathan G. Murnick, Jeffrey D. Erickson, and Guosong Liu, which appeared on pages 6221-6234 of the June 29, 2005 issue, the raw data trace for "VGLUT+" in Figure 4C erroneously printed as a duplication of the raw data trace for "Control" in the same panel. This illustration error does not affect in any way the results and conclusions of the paper. The correct version of Figure 4, as well as the legend, is printed here.

Figure 4. Effects of VGLUT1 overexpression on quantal excitatory transmission. A, mEPSCs were recorded postsynaptically via a whole-cell patch clamp in the presence of TTX either in a network completely lacking VGLUT1 overexpression (Control) or from a subregion of a transfected network visually determined to be dense in overexpressing neurons (VGLUT+). B, Distributions of mEPSC amplitudes observed in the neurons shown in A. VGLUT+ events tend to be right-shifted relative to the control event distribution. C, Sample mEPSCs from cells recorded in control and VGLUT+, which in this case are an average of 48% larger in the VGLUT+ recording. Calibration: 10 pA, 150 ms. D, Average mEPSC amplitude for neurons recorded in each group shows an increase in VGLUT+ mean event amplitude (*p = 0.04; unpaired t test). mEPSC data are aligned with the EPSC amplitude data from Figure 3C. E, No significant difference between control and VGLUT+ neurons is observed for mEPSC frequency (shown here) or rise and decay time kinetics (data not shown). Error bars indicate SEM.
