Figure 1

A heatmap of the top 100 genes in each tissue (1000 genes total), based on z-scores (tissues are labeled on the x-axis, and genes are the y-axis). The scale associating the color with the z-score for any given gene is shown on the right. A measure of similarity between tissues is reflected in the degree of positive scores on the off-diagonal. This similarity is most clearly illustrated between the optic nerve and the optic nerve head.
