The human brain is so complex that scientific brains have a hard time making sense of it. A piece of neural tissue the size of a grain of sand might be packed with hundreds of thousands of cells linked together by miles of wiring. In 1979, Francis Crick, the Nobel-prize-winning scientist, concluded that the anatomy and activity in just a cubic millimeter of brain matter would forever exceed our understanding.<\/p>\n\n\n\n
\u201cIt is no use asking for the impossible,\u201d Dr. Crick wrote<\/a>.<\/p>\n\n\n\n Forty-six years later, a team of more than 100 scientists has achieved that impossible, by recording the cellular activity and mapping the structure in a cubic millimeter of a mouse\u2019s brain \u2014 less than one percent of its full volume. In accomplishing this feat, they amassed 1.6 petabytes of data \u2014 the equivalent of 22 years of nonstop high-definition video.<\/p>\n\n\n\n \u201cThis is a milestone,\u201d said Davi Bock, a neuroscientist at the University of Vermont who was not involved in\u00a0the study<\/a>, which was published Wednesday in the journal Nature. Dr. Bock said that the advances that made it possible to chart a cubic millimeter of brain boded well for a new goal: mapping the wiring of the entire brain of a mouse.<\/p>\n\n\n\n Read it all<\/a>.<\/p><\/p> An Advance in Brain Research That Was Once Considered Impossible https:\/\/t.co\/peoDcslro2<\/a>
Scientists achieved \u201ca milestone\u201d by charting the activity and structure of 200,000 cells in a mouse brain and their 523 million connections.<\/p>— Paul Higgins (@futuristpaul) April 9, 2025<\/a><\/blockquote>
