Growth Factors Help Neurons to Reach Their Correct Destination
...the nerve cells through a series of attractive and repulsive
chemical. While several recent studies discovered molecules that repel motor neuron axons from incorrect targets in the limb, scientists at the Salk Institute for Biological Studies have identified a molecule, known as FGF that actively lures growing...
Chemical Signaling Helps Regulate Sensory Map Formation In The Brain
...ncentrations of Wnt3 and the other driven away. "A repulsive
Wnt-Ryk pathway competes with an attractive Wnt-Frizzled interaction," the authors write, "to titrate the response to Wnt3 protein at different concentrations." The net outcome of the competition, they conclude, "determines the topographic connection...

...n there was more of plus rather than minus form. A repulsive
effect was observed when there were equal proportions of both forms. Rasmussen added: "All of these responses and resultant behaviors are measurable in time. Not milliseconds, but seconds. We have a repertoire of follow-up behavior, such as trumpet...
