Relation between effects of age and side on gene expression (as t-values) for the brain structures aged 5–5.5pcw and aged 7.5–13pcw. Each dot is an individual gene. X-axis: left-right differential expression t-value, with positive values indicating genes with higher right-sided expression. Y-axis: age-effect t-value, where positive t-values indicate genes which increase in expression with age. A positive age-side correlation therefore indicates that the right side of a structure leads the left side in the transcriptional changes which both sides follow. R- and p-values can be found in the main text. Note that for the midbrain and the forebrain t-values for age and side were not computed on the same samples (see main text).
