Methylation in human cerebellum and frontal cortex tissue. (A) Kernel density estimation function of average gene methylation. Gaussian mixture models were used to classify the genes into Non-, Medium- and Highly- methylated clusters. (B) Kernel density estimation function of average gene methylation by EV classification. The dashed vertical lines represent the methylation state cluster cut-offs generated by the Gaussian mixture modelling
