The world’s first holograms of the electrical activity of the mind are now a reality.As a result of an extensive collaborative team effort led by leading holographer, Professor Michael Page of OCAD University and Cerebral Diagnostics Canada Inc, the project involved, programmers, a physician, holographic researchers, photographers and an electrical engineer. Our team has developed a technologically sound and brain-activity hologram product that is now ready for sale. This project integrated state of the art holographic technology with state of the art 3D graphics of the electrical activity of the human brain.

Holograms make exciting and permanent 3D hard copies. Prior to the start of the project, Cerebral Diagnostics Canada Inc. had developed an exclusive 3-D brainwave imaging and recording system called DECI which stands for Dynamic Electrical Cortical Imaging. It is an EEG based system but it measures from many electrodes and then uses a specialized mathematical algorithm (called an inverse solution) to find the generators of EEG waves. This allows them to make pictures of the brain with colours marking areas of activity and the direction of current flow in the brain. The data is mapped to a 3D construct. Much in the same way that people send documents to their printers, our technology connects one of the world's most advanced brain scanning systems in the world to the most advanced holographic printers.

What is a Direct Write Hologram?

Unlike conventional holography, where a master hologram is produced and then copied into the final hologram, state-of-the-art holograms utilize a direct write technique. This involves printing hogels (holographic pixels) directly onto the finished hologram. This has significant advantages over conventional holography. Each hogel possesses density (i.e. RGB colour) information as well as phase information. It is common to have almost a half million hogels in a poster sized hologram. Large mural-sized holograms have been demonstrated.
