A rotatable brain built from an MRI atlas, with colored anatomical sections drawn as a wireframe. Drag to spin it, scroll to zoom — it all runs right in your browser.

This is the average T1-weighted MRI brain atlas (the same reference volume used across neuroimaging research), turned into a 3D surface. The scan's intensity values are grouped into a handful of tissue "sections," and the boundaries between them are contoured and auto-colored — so each colored shell roughly traces a different density of brain tissue.
Best viewed on a device with WebGL support (virtually every modern phone and desktop browser).
The 3D brain viewer is an interactive wireframe model of the human brain built from medical MRI atlas data. Colored anatomical sections let you see the brain's major regions and structures. You can spin it, zoom in and out, and pan around right in your browser — and it works offline once loaded, so no data is sent anywhere.
This is an educational tool for curiosity and learning. If you're interested in neuroscience, preparing for a biology class, or just want to explore what's inside your skull in 3D, this viewer makes it easy and hands-on. The model is rendered with WebGL, a standard browser technology, and requires no downloads or special software.
Click and drag your mouse across the brain to rotate it. Scroll your mouse wheel or pinch on a touchscreen to zoom in and out. Hold Shift while dragging to pan the view around. The model loads once and then works completely offline — no uploads, no tracking. You can view it as many times as you want with no data collected.
Is this medically accurate?
The model is based on standard MRI atlases used in medical education, so the anatomy is solid. That said, every brain is unique. Use it for learning and curiosity, not for self-diagnosis or medical decisions. If you have health concerns, consult a doctor.
Do I need special software to use it?
No. Any modern web browser works. It's built with WebGL, which is built into all current browsers.
Will it work on my phone or tablet?
Yes. The controls work with touch — drag to rotate, pinch to zoom.
Can I download the 3D model?
The model data stays in your browser. You can take screenshots of views you like, but direct download isn't available.
