Nell’s Brain
γνῶθι σεαυτόν — know thyself. Carved over the temple at Delphi; here, taken a little literally.

Orientation and controls
Radiological convention places Nell’s left on your right. R and L mean right and left; A and P mean anterior and posterior; S and I mean superior and inferior. Drag a crosshair, use the mouse wheel, or press the arrow keys to travel through slices.
The 3D canvas displays MRI-derived anatomy. Use Find anatomy to select a named structure, or press Enter on the canvas to identify its centre point.
About this scan, labels, and privacy
Fine cortical and deep-brain labels come from atlas-backed segmentation. Broad skin, muscle, fat, and bone classes are derived tissue labels; the three bone groups are approximate. Facial colour and studio lighting are cosmetic presentation layers and do not alter the MRI anatomy. The public viewer receives the same static atlas as every visitor and uploads nothing.
This is my actual head, scanned as a T1 MRI at the Centre for Neuroimaging Sciences — a small digital backup of my brain, every fold and fissure of it, displayed live in your browser. Spin it as a solid object and cut it open, colour it by anatomy — thalamus, hippocampus, the cortical gyri, from my own brain map — or switch to slices and travel through it plane by plane. Real voxels — no download, no plug-in.
Slices are shown in radiological convention — my left is on your right. This scan has also served in AI interpretability experiments, matching activations in artificial minds against the structure of a real one. Prefer the real thing? The full-resolution scans (whole head and brain-only, NIfTI) are yours to download — one file of just the brain, one of the whole head; the full body and the high-res connectome I’ll hold back, if you don’t mind. More to play with on the Playground; and What If We Feel? is, cover to cover, the argument that all minds deserve such interpretability.
