Correction: In the article ‘Gap Junctional Coupling Underlies the Short-Latency Spike Synchrony of Retinal α Ganglion Cells’ by Edward H. Hu and Stewart A. Bloomfield, which appeared on pages 6768–6777 of the July 30, 2003 issue, the authors did not obtain permission to reproduce the images in Figure 1, C and D, which had been previously published in an article by Hu et al. (2000) [Hu EH, Dacheux RF, Bloomfield SA (2000) A flattened retina-eyecup preparation suitable for electrophysiological studies of neurons visualized with trans-scleral infrared illumination. J Neurosci Methods 103:209–216]. Permission to reuse the figure panels has since been granted.
