In this article, the authors have identified errors in the captions of Figures 2 and 6.

Page 763, Figure 2a caption, line 3, the second sentence should be ‘The distances covered by the C57BL/6J mice at 3 months of age were significantly lower than those covered by the C57BL/6J mice at 6 months (P<0.01) and 12 months (P<0.01) of age.’ Figure 2b, line 9, the second sentence should be ‘The TS and NS for the C57BL/6J mice at 3 months of age were significantly higher than those of the C57BL/6J mice at 6 months (P<0.05) and 12 months (P<0.05) of age.’

Page 767, Figure 6 caption, line 8, the second sentence should be ‘(c) At all ages, neither strain showed a bias of the Lm within each field (upper, middle, lower) at the same age. One-way analysis of variance did not reveal any statistically significant differences in the C57BL/6J mice and the pallid mice.’
