A whole mouse brain is about 31 terabytes of imaging data, about 32 million digital photographs.

The technology known as ViSUS has been used for years in several different areas of research, including clean energy simulations on high performance computing platforms. The software processes interactively terascale-sized datasets. The typical laptop has about 4-to-15 gigabytes of memory. One terabyte has 1,000 times that much. A whole mouse brain is about 31 terabytes of imaging data. That is the same amount of data as about 32 billion digital photographs. The visual cortex of the macaque brain, which Angelucci studies, is 318 terabytes -- 100 times more.
