Schematic outline of data analysis. HCL: hierarchical clustering. ^a Brain gene expression prior to infection was compared with brain gene expression on days 2, 5 and 7. ^b Brain gene expression in CM-R mice was compared with that in CM-S mice at each time point. As represented by dashed arrows, we considered the whole data set (n = 2012 genes) to carry out multiple testing correction.
