Charting a larval fruit fly’s nerve cells and their connections took 12 years...
The wiring of one insect’s brain no longer contains much uncharted territory.
All of the nerve cells — and virtually every connection between them — in a larval fruit fly brain have now been mapped and it’s the most complex whole brain wiring diagram yet created.
Previously, just three organisms — a sea squirt and two types of worm — had their brain circuitry fully diagrammed to this resolution. But the brains of those creatures have only a few hundred neurons. The scientists who conducted the new study wanted to understand much more complicated brains.
Fruit flies (Drosophila melanogaster) share a wide range of behaviors with humans, including integrating sensory information and learning. Larvae perform nearly all the same actions as adult flies — except for some, like flying and mating — but have smaller brains, making data collection much faster.
The researchers identified more than 3,000 neurons and about 550,000 connections, known as synapses.
