anatomical brain model 3d

Create a highly realistic anatomical 3D-style render of a human brain only, isolated on a clean white background. Show the brain as a single solid full brain with one clean planar cutaway section removed, like an anatomical teaching model. The exterior brain should remain visibly intact around the top, back, right side, and lower edges, with natural gyri and sulci wrapping around the full volume. The cutaway should expose one flat coronal cross-section face on the front-left side of the brain only, revealing realistic internal brain anatomy such as gray matter, white matter, ventricles, corpus callosum, thalamus, brainstem connection, and cerebellar tissue where appropriate. The cut face must be a single flat vertical plane with visible thickness at the edges, not a thin slice and not a 360-degree cross-section. Use a 3/4 front view, slightly above eye level, so both the exterior full brain shape and the single exposed cross-section plane are clearly visible.
