Brain Functional Differences Reflect Anatomy, Lifestyle, and Environmental Influences
Researchers at Beijing Institute of Technology used Human Connectome Project data to map how ethnicity‑related brain functional differences arise. They found that functional topography follows a sensorimotor‑association axis and is tightly constrained by underlying anatomy. Lifestyle factors such as education level and substance use mediate these differences, reshaping connectivity in control hubs. Gene‑expression analysis shows the patterns align with synaptic‑signaling genes, suggesting post‑natal environmental influences outweigh innate genetic ancestry.
