Scientists mapped a piece of brain the size of half a grain of rice.One-millionth the size of the human brain.It took them a year and over 1.4 million gigabytes to scan it.They found over 57,000 cells, 150 million synapses, and even some new structures they didn't know existed.Mapping the entire human brain in this level of detail would require all the data storage generated on Earth in a year + a 140-acre data center.But the human brain itself can hold up to ~2.5 million gigabytes of informatio
