The original version of this Article contained an error in Figure 1D, where the y-axis label “Puncta Density (Number per 200 μm2)” was incorrectly given as “Puncta Density (Number per 20 μm2)”.
The original Figure 1 and accompanying legend appear below.

Mapping PSD95-eGFP PSDs in the Mouse Spinal Cord. (A) High magnification tiled imaging was performed on half-spinal cord sections from PSD95-eGFP mice from three age groups (n = 3 mice per age group). Quantitative analysis was performed at the single synapse level to study synaptic diversity between laminae and across age groups. (B) Example images of PSD95-eGFP PSDs in three laminae from each age group. Note the formation of large elongated PSDs in VII of Adult and Aged mice. (C) The mean ‘field’ intensity of PSD95-eGFP labelling was quantified from entire delineated laminae at each age. Age groups are colour coded as Young (blue), Adult (orange) and Aged (grey). Colour-coded lines indicate statistical significance between laminae within an age group following a post-hoc test. The PSD density (number per unit area) (D), the mean fluorescence intensity of PSDs (E) and the median PSD size (F) is also plotted for each lamina in each age group.
