Brain Protein "Rescues" Neurons From Atrophy
... neurotrophins. Such a differential response would help
confirm that neurotrophins are not simply a general growth enhancer for neurons, but represent a sort of chemical "language" that specifically regulates how different kinds of neurons develop. In their experiments, the scientists provided different n...
