Scientists achieved “a milestone” by charting the activity and structure of 200,000 cells in a mouse brain and their 523 million connections.
In 1979, famed molecular biologist Francis Crick stated that it would be “impossible to create an exact wiring diagram for a cubic millimeter of brain tissue and the way all its neurons are firing,” which inspired Allen Institute’s Senior Investigator Clay Reid to pursue the subject as his life’s work.
From a tiny sample of tissue no larger than a grain of sand, scientists have come within reach of a goal once thought unattainable: building a complete functional wiring diagram of a portion of the brain.
