Running along each side of the back of a squid is a tube-like structure that can be as large as 1.5 mm in diameter in some species. Originally thought to be blood vessels, in the late 1930s the anatomist J.Z. Young discovered that the structures are connected to the nervous system, not to the heart. Although the vast majority of axons in the squid range in diameter from about 10 μm to 50 μm, as squid develop, axons from about...
