Scientists have generated the first complete map of the brain of a small insect, including all of its neurons and connecting synapses.
The research, published on 9 March in Science1, provides a brain-wiring diagram known as the connectome of a complex animal for the first time — the fruit fly Drosophila melanogaster. The map shows all 3,016 neurons and 548,000 synapses tightly packed in a young Drosophila’s brain, which is smaller than a poppy seed.
The map is a milestone in understanding how the brain processes the flow of sensory information and translates it into action.
