For accuracy, brain studies of complex behavior require thousands of people

Scientists rely on brainwide association studies to measure brain structure and function — using brain scans — and link them to mental illness and other complex behaviors. But a study by researchers at Washington University School of Medicine in St. Louis and the University of Minnesota shows that most published brainwide association studies are performed with too few participants to yield reliable findings.

Studying mice, Washington University School of Medicine researchers have discovered that roseolovirus can trigger autoimmunity in a previously unknown way: by disrupting the process by which immune cells learn to avoid targeting their own body’s cells and tissues.
