Correction to: Acta Pharmacologica Sinica https://doi.org/10.1038/aps.2016.115, published online 14 November 2016

The authors apologize that one image in Fig. 2a appeared incorrectly. The representative image for the positive control “NGF” group in Fig. 2a is the same as that for the “10 μmol/L ARDD in D4” group in Fig. 2c. The correct picture for the positive control “NGF” group in Fig. 2a is given. This correction does not affect the conclusions of the original article. We apologize again for any inconvenience caused.

Fig. 2: ARDD induces neurite outgrowth of N1E115 cells.
figure 1

a Effects of different doses of ARDD on neurite outgrowth of N1E115 cells at day 4. The bar represents 100 μm. b Statistics of average neurite length in above groups at day 4. The data are expressed as the mean ± SEM (n = 80–100). ***P < 0.001 vs control group. c Time-course manner of 10 μmol/L ARDD promoting neurite outgrowth of N1E115 cells. The bar represents 100 μm. d Statistics of average neurite length at different days. The data are expressed as the mean ± SEM (n = 80–100). **P < 0.01, ***P < 0.001 vs control group.

The correct Fig. 2 is shown below.
