Google maps mouse brain
Researchers on Google's Connectomics team have achieved the largest AI-assisted digital reconstruction of human brain tissue to date. Now, they are turning their attention to the mouse brain to further unravel the mysteries of neural connections.
The recent accomplishment involved mapping just 1 cubic millimeter of human brain tissue, a task that required an astounding 1.4 petabytes of data. This tiny section, equivalent to half a grain of rice, revealed unexpected structures within neurons. "We found some of the wires will wrap themselves into these giant knots," says Google Research Scientist Viren Jain. "We have no idea why -- nobody's ever seen it before."
