White matter fibers, HPC Dataset side view. White matter fiber architecture of the brain measured from diffusion spectral imaging. The fibers are color coded, red is left, green is anterior/posterior, blue is up/down - Laboratory of Neuro Imaging and Martinos Center for Biomedical Imaging at Massachusetts General Hospital, Human Connectome Project funded by National Institute of Health 

The Human Connectome Project is going deep and then deeper. It is allowing one to “Navigate the brain in a way that was never before possible; fly through major brain pathways, compare essential circuits, zoom into a region to explore the cells that comprise it, and the functions that depend on it.”

The Project provides an unparalleled compilation of neural data, an interface to graphically navigate the data, and the opportunity to achieve never before realized conclusions about the living human brain. It works with one group of fibers in the brain at a time tracking their principle axes.

Brain imaging like fMRIs are not the same thing as brain recording. Brain recording allows doctors to implant sensors in people’s brains with real time feedback of how the brain is talking or communicating with other parts of the brain. It shows live-time how neural circuits route and function.

The actual scanner, a Siemens 3T Connectom scanner which looks like lots of coils wrapped around a tube that you slide into.

LONI Probablistic Brain Atlas - fMri images of regions of the brain - pretty in pink!

Their goal is to make a brain atlas for everyone!

I think Anni Albers of the Bahaus would have a lot to say about this!

Meanwhile, Google Glass and NeuroSky made a video for CNN where a reporter concentrated on a plate of fruit. If she concentrated strongly enough, she was able to command Google Glass to take a photo.

However, over 100 years ago Paul Cezanne thought about fruits in a bowl as well. He must have stared and concentrated long enough to take 1000 Google Glass photos!

This reinforces my view when it comes to computer vision and human computer interface artists saw it first, and did it first!
