MRI / 01 Brain, Layer by Layer

An open-data neuroanatomy study

See a brain as a radiologist does. Then take it apart.

Move a coronal plane from the face toward the back of the head. Read real atlas labels in place. Then switch from slices to a removable anatomical model and uncover what sits beneath the cortex.

Data & method

A reference atlas, not a diagnosis.

The MRI passage pairs the population-averaged MNI-ICBM152 2009c symmetric T1 template with CerebrA’s manually corrected 102-label atlas in the same 1 mm coordinate space. The removable model is the NIH 3D Human Reference Atlas brain, derived from the Allen Human Reference Atlas—3D, 2020. Its mesh identities are cross-checked against the original Allen 0.5 mm annotation volume.

Templates describe shared anatomy, not every person’s brain. The removable model mirrors one annotated hemisphere, so variable folds—including the paracingulate gyrus—appear bilaterally. Boundaries are atlas estimates; image contrast is educational and must not be used for clinical interpretation.
