Theoretical bounds on the change detection in brain volume measurements

Many neurodegenerative disorders, psychiatric disorders, and healthy aging are frequently associated with structural changes in the brain. As the brain develops over time, the cortical surface area, thickness, curvature and total gray matter volume change. It is highly likely that such age-relate...
