In the article “The Diversity of Ganglion Cells in a Mammalian Retina,” by Rebecca L. Rockhill, Frank J. Daly, Margaret A. MacNeil, Solange P. Brown, and Richard H. Masland, which appeared on pages 3831-3843 of the May 1, 2002 issue, an incorrect version of Table 1 was inadvertently published. A coverage factor of 1.4 for retinal ganglion cells was assumed, rather than 1.8 as stated in the text. This slightly changes the values for the predicted density of retinal ganglion cells. None of the conclusions of the paper are affected. A revised version of the table is printed here.
In addition, on page 3840, left column, line 33 of the text, the predicted total should be 397 cells/mm2, not 307 cells/mm2.
