Figure 7. Brain network connectivity differences among primates.
The human olivedrab2 FP module as an example of differential connectivity in the primate brain. (A) Histogram of the difference in connectivity among genes in the olivedrab2 module between each species. Human networks compared to chimpanzee (blue) and macaque (red) networks have greater differences than between chimpanzee and macaque (grey). Unrooted distance trees demonstrate that while human and chimpanzee are more similar as (B) species overall and (C) absolute gene expression, while the (D) connectivity of genes in the human FP is greater.
