Brain Gene Tops the List for Making Humans, Human

WebHuman brain development has been studied intensively with neuroimaging. However, little is known about how genes influence developmental brain trajectories, even though a significant number of genes (about 10,000, or approximately one-third) in the human genome are expressed primarily in the brain and during brain development. WebNov 18, 2015 · In their prior work (2–4), the authors discovered “modules” of genetic organization in the human brain: clusters of key brain systems, each shaped by a common genetic blueprint.With this new genetic map of the brain as a guide, Fjell et al. now show how these genetic modules change in unique ways, as we progress through life, using … floral arranging class near me
