Mean expression of the mitochondria pathway genes plotted against mean expression of the synapse pathway genes for the three indicated microarray datasets. a–c Mitochondrial gene expression and synapse gene expression were correlated in the Voineagu et al. (a), Chow et al. (b), and Garbett et al. (c) datasets. Correlation coefficients (cor) are shown and reflect a very high level of correlation
