This is the most accurate 3D map of a brain: 20 million synapses connecting 25,000 neurons that you can explore

The brain is one of the most complex parts of an organism, thousands and thousands of neurons connected to each other to send electrical impulses that make the rest of the living being work. To put the magnitude of this system into context, a team of researchers has created a precise three-dimensional map that shows a brain with more than 25,000 neurons connected. And it is that of a simple fly, not even close to the brain of a human, but it is still surprising.
