Definition
Abnormal brain structure refers to any atypical or deviant physical characteristics or arrangements in the brain that are different from what is typically observed. It can include variations in size, shape, or organization of brain regions.
These are conditions characterized by atypical development of the nervous system during early childhood, such as autism spectrum disorder (ASD) or attention-deficit/hyperactivity disorder (ADHD).
This imaging technique uses magnetic fields and radio waves to create detailed images of the brain's structure. Researchers can use MRI scans to identify and study abnormalities in brain structures associated with neurodevelopmental disorders.
Functional Connectivity: This term refers to how different areas of the brain communicate and work together during specific tasks or at rest. Studying abnormal brain structures also involves investigating their impact on functional connectivity within neural networks involved in neurodevelopmental disorders.
