In Fig 1C, the DA and GLU panels of the DG row were inadvertently duplicated. The DA panel has been replaced in the corrected panel below.

In addition, there is a duplication of the DA and GLU panels in Fig. 4A. The authors no longer have the original data for these panels but note that the results shown in Fig. 4A (in situ hybridisation with c-fos probe) have been repeated by many other researchers and are also shown using in situ immune-hybridization in Fig. 4B.

Phosphorylation of histone H3 is induced in the hippocampus by stimulation of DA, mACh and GLU receptors. (C) Phosphorylation of histone H3 in the DG and in the CA3 after stimulation of DA, mACh and mGLU receptors.
