The incorrect and correct figure and its caption are published in this Correction article. The original article has been updated.

Incorrect figure:

Fig. 1 Number of Fos-positive neurons in the hippocampus before and after exposure to a novel environment. ac Number of Fos-positive neurons (left) and representative images (right) from WT and DD mice after 0–4 h of exposure to a novel environment in the CA1 (a), CA3 (b), and DG (c) (n = 6/group). The data are expressed as mean ± SEM. **p < 0.01, compared with 0 h; ##p 0.01, compared with WT mice. Scale bar = 200  μm
