Scientists of IIT Madras have made a surprising discovery using the brains of five fetuses. They have made a perfect brain map through that fetus of only 14 to 24 weeks of age. To make it, the embryos were first sliced thinner than a human hair. A detailed 3D map of the brain with over 5,000 images is then created using Indian technology. This unique map is made at a cost of about 10 times less than the cost of the same research in foreign countries. Scientists believe the atlas will help doctors and researchers better understand the human brain.

How this Human Brain Atlas can help
Professor Mohanshankar Sivaprakasam, who led the project at IIT Madras, said that no one had seen the brain so closely before. He and his team have created very detailed images of the brain that show how the brain changes and functions at different ages. Its goal is to help doctors better understand the brain and help find ways to treat diseases such as Parkinson’s, Alzheimer’s and stroke. He also said that it has been decided to make this brain map available to all for free, so that anyone can use it if required.

More than 200 brains, including both healthy and diseased brains, were collected to create this map. At least 70 have used special techniques to create detailed digital images of the brain. More than 500 different parts of the brain are identified in this brain map.
Planning to create these high-resolution 3D brain images began in 2015 after discussions with IIT-M alumnus and Infosys co-founder Chris Gopalakrishnan. He believes that this research will help treat diseases and also open new opportunities in artificial intelligence and machine learning. He also said, “In order to use advanced artificial intelligence, we first need to understand human intelligence.” It is learned that Gopalakrishnan has also given money to this particular Atlas project. The findings were published in the 132-year-old journal Comparative Neurology.
