UK scientists have released the first batch of “groundbreaking” medical scans that reveal step-by-step how the human brain develops in babies. Researchers around the world can use the data to understand what healthy growth looks like, say the Developing Human Connectome Project experts. The detailed MRI scans could also improve understanding of conditions such as autism and cerebral palsy.  They precisely plot how the billions of neurons form and connect together. The team from King’s College London, Imperial College London and the University of Oxford say their task has been incredibly challenging.  Newborn human brains contain trillions of pathways, packed into an organ that is about the size of a small tangerine.  So far, the scientists have released data they collected by scanning 40 babies a few days after birth.  Lead investigator Prof David Edwards said getting permission from new parents to allow their babies to be scanned was “a big asks”.  “It’s perfectly safe. There’s no radiation or X-rays involved. But we are incredibly grateful to the families who have taken part in this work. It’s contributing hugely to science.” Their plan is to scan many more newborns, as well as babies still growing in the womb. Then they will create a dynamic map of human brain connectivity.  Prof Edwards said: “Having lots of data will mean we can study what is normal and abnormal in terms of brain development.
