This is my brain's cortical surface, reconstructed from a research MRI with FreeSurfer 7.4.1. It's an anatomical visualization, not a medical image or a diagnosis. The backdrop can show a live 3D model of the cortex, slices of the T1 MRI (brain only, resampled to 1.5 mm), or a still image. The Explore page adds deep structures and a movable MRI slice plane. Every cortical region is also listed as text on the About page.

Scrolling this page moves an axial cut down through the cortex. The cut face shows the cortical ribbon and the white matter inside it, both from the same reconstruction. You can also move the cut with the slider.
