Cost-efficiency was found to have a strong genetic basis, with 60% of the variation explicable through genetic variation. These differences in efficiency were particularly marked in certain areas of the brain, including the prefrontal cortex which carries out functions such as decision-making and planning.
These findings could have important implications not only in suggesting new directions for future brain research, but also in the understanding of mental illnesses. For example, brain network wiring was found to be significantly less cost-efficient in patients diagnosed with Schizophrenia. The research may therefore help uncover which specific genes are central to mental disorders and neurological diseases and offer new possibilities for treatments [2].
