By Nell Boyce THE secret to wiring the brain might be a protein that comes in tens of thousands of different forms. As the brain develops, over a trillion neurons send out fibres called axons to link to distant neurons, guided by chemical signals from neighbouring cells. Relatively few guidance molecules are known, so it’s hard to understand how all these neurons manage to make precise connections. That’s why the discovery of a receptor on fruit fly neurons that comes in many thousands of different forms has excited scientists,
