Network of 75 Million Neurons of the Mouse Brain Mapped for the First Time Network of 75 Million Neurons of the Mouse Brain Mapped for the First Time With improved visualization tools and souped-up computers to crunch the massive numbers involved in studying the 100 billion neurons in the human brain, many researchers, including the U.S. government, are trying to map the brain’s wiring, or “connectome.” Some researchers have dived right in to studying the massive human brain, but others see the mouse brain, with just 75 million neurons, as a more logical place to start. A new atlas of study results related to the mouse connectome offers the equivalent of a highway map, with local roads to be filled in later. It’s the most detailed information we have on the brain of any animal other than that of the roundworm C. elegans, which has just 302 neurons. “Understanding how the brain is wired is among the most crucial steps to understanding how the brain encodes information,” project lead Hongkui Zeng said in a news release. But there’s a long way to go.
