The Allen Institute is committed to solving mysteries of bioscience — researching the unknown of human biology, in the brain, the cell and the immune system.
The first cellular map of a mammalian brain is here. 🧠✨
Over 6 years and 32 million cells in the making, the complete adult mouse brain cell-type atlas reveals astonishing diversity and regional specificity.
