A new map showing 50 million neural connections is a 'huge leap' to understanding our own brains.

Now for the first time scientists researching the brain of a fly have identified the position, shape and connections of every single one of its 130,000 cells and 50 million connections.

It’s the most detailed analysis of the brain of an adult animal ever produced.

One leading brain specialist independent of the new research described the breakthrough as a “huge leap” in our understanding of our own brains.
