Scientists have mapped an insect brain in greater detail than ever before

Charting a larval fruit fly’s nerve cells and their connections took 12 years

This diagram shows every nerve cell (multicolor) in a larval fruit fly brain, with the spheres representing the cell body and the elongated tails as branches that send and receive information. The connections, known as synapses, aren’t visible here.
