A team of researchers made a detailed biological map of the brain. They combined brain scans with genetic data and molecular imaging to link small parts with large brain systems.
The study looks at changing patterns of activity, called dynamic connectivity. The researchers measured cells, chemical messengers such as serotonin and dopamine, and mitochondria. They used a statistical method to show that brain networks can explain how molecular features influence cognition. The lead authors include Vince Calhoun and Guozheng Feng. Funding came from the National Science Foundation and the National Institutes of Health.
