The caption for figure 2 is incorrect. It should read:
Figure 2. LS mean ± s.e.m. frequency (a) and duration (b) of burrowing, climbing and upright standing per day per rat at three, eight and 13 months of age in semi-naturalistic cages. Data are mean ± s.e. based on four cages housing five rats at three months, and six cages housing five (n = 4) or four (n = 2) rats at eight and 13 months; *p < 0.05 and ***p < 0.001.
