Figure 4From: Functional associations among G protein-coupled neurotransmitter receptors in the human brainGraph representations of receptor correlations. A, A graph representation of all significant correlations between receptors (after the Bonferroni correction; all Cookâs distances do not exceed 1.0). The inset shows the distribution of the vertex degrees. B, The neighborhood subgraph of the nociceptin receptor (OPRL1); marked in the center.Back to article page
