Summary:
A human hormone known to stimulate the growth of cells throughout the body has a new role - helping to set up the proper nerve connections in the odor center of the brain, according to University of California, Berkeley scientists. Now, neuroscientists have shown that IGF also controls the direction of axon growth as axons stretch from the nose's odor detectors to the brain's olfactory bulb. Axon guidance represents a new role for IGF in development.
