sulcal depth map
Three-dimensional representation showing the depth of brain sulci measured from the cortical surface to the deepest point of each fold.
Full Definition
A sulcal depth map is a neuroanatomical visualization tool that quantifies the depth of cortical sulci (brain folds) by measuring the distance from the cortical surface to the deepest point within each sulcus. These maps are generated from high-resolution structural MRI data and are used to study cortical folding patterns, identify anatomical landmarks for registration, and investigate developmental or pathological changes in brain morphology.
Usage
Usage note: Keep as compound term; avoid separating into 'sulcal depth' and 'map' in technical contexts.
