In the article “Stages of Synapse Development Defined by Dependence on F-Actin,” by Wandong Zhang and Deanna L. Benson, which appeared on pages 5169–5181 of the July 15, 2001 issue, Figure 9 was incorrectly printed without the correct gray shading. The correct version of the figure, as well as the legend, is printed here.
Fig. 9.
Juxtaposed against a time line summarizing major developmental events in cultured hippocampal neurons are synaptic proteins that are written with black, medium gray, or light gray to depict their dependence on F-actin for their synaptic localization (black = most dependent). Molecules restricted to excitatory synapses are indicated by (+).
