Harvard and Google spent 10 years mapping a 1 cubic millimeter section of the human brain, resulting in 1.4 petabytes of data, equivalent to 1.4 million gigabytes. This project involved slicing the tissue into 5,000 wafers and using a $6 million electron microscope, along with Google's machine learning models for 3D reconstruction.

The full human brain is estimated to yield 1.4 zettabytes of data, requiring a 140-acre data center at a cost of $50 billion. The next phase will involve mapping a mouse hippocampus over the next five years.
