The mRNA expression profiles of six neurotransmitter receptors. The horizontal axis represents the 169 brain regions and the vertical axis represents the mRNA amounts (averaged across the probes and subjects). Since the numerical mRNA values are normalized and relative, they are not indicated on the vertical axis (for all six genes, it ranges from −2 to 2). Note high similarity between some of the profiles (e.g., mGluR1 and CRF1, 5-HT2A and H1).
