In their PLoS Genetics paper, Gibbs et al generated nearly genome-wide measurments of mRNA and methylation levels for 150 individuals, across 4 different brain regions.
The expression and methylation datasets are both available from the publication's GEO repository, which also includes microRNA data from the same subjects.
