A newly discovered signaling molecule helps neurons find their way in the developing brain

Commissural neurons in a mouse embryoIn the developing nervous system, some neurons must extend their branches to connect one half of the brain with the other. A new study sheds light on the molecular mechanisms that guide the winding paths of their axons. More »

Netrin molecules help neruons shed their symmetry

For years, scientists have known that netrin molecules help guide growing neurons and their axons — the long tendrils that conduct electrical signals. But new research shows that these proteins are also important for helping create the neuron’s characteristically asymmetrical shape. More »
