In a feat that seemed unachievable just a few short years ago, an international research consortium has recently unveiled the first complete wiring diagram of an entire fruit fly brain. The map itself is accompanied by a cache of papers, demonstrating how this breakthrough is already leading to new scientific findings and there’s much more to come.
Why do we need brain maps anyway? Maps that show every neuron in a brain and all the myriad connections between them are called connectomes. The fi
