About this work


Side view of connections in the brain of a healthy 29 year old female human as interpreted by Google's Deep Dream software. The brain is viewed as if looking through the head from a person's right ear. The front of the brain is facing the right side of the image and the back of the brain is on the left. This image was created by first visualising nerve fibres in the brain using diffusion imaging tractography. The resulting image was then passed through Google's Deep Dream software. Diffusion weighted imaging is a specialised type of magnetic resonance imaging (MRI) scan which measures water diffusion in many directions in order to reconstruct the orientation of bundles of axons. Tractography is used to indirectly model these bundles of axons (nerve fibres), which transmit information between cortical regions at the brain's surface. The brain measures approximately 18 cm from front to back.
