voxel-based morphometry (vbm)
Voxel-based morphometry (VBM) is a neuroimaging technique used to analyze and compare brain structures across individuals or groups. It involves measuring and statistically analyzing differences in the concentration or volume of gray and white matter in three-dimensional "voxels" (the 3D equivalent of pixels) within brain images obtained from magnetic resonance imaging (MRI) scans. VBM helps identify brain regions that may be associated with specific conditions or diseases and provides insights into structural variations in the brain.
