A figure showing hierarchical clustering of drug-induced gene expression alterations in mouse striatum. Microarray results are shown as a heat map and include genes with a significance obtained from two-way analysis of variance of the drug factor at (a) 5% and (b) 29% of FDR. Colored rectangles represent the transcript abundance (Additional file 5) of the gene and are labeled on the right. The intensity of the color is proportional to the standardized values (between -2 and 2) from each microarray, as indicated on the bar below the heat map image.
