    Insight into seeing

    Harvard-affiliated researchers have been able to make a comparison of neurons in optic nerves to learn more about why some regenerate and others don’t.

    Barrier found to nerve regeneration

    Scientists have long dreamed of prompting adult neurons of the central nervous system to regenerate. But these cells have the deck stacked against them in several ways. Molecules from the myelin sheath surrounding their axons actively discourage growth. After injury, nearby astrocytes form a dense scar to block them. Even the signals that once guided…

    Brake on Axon regrowth discovered

    Since nerve cell axons in the mature central nervous system do not regrow, neurologists have no way of fully treating paralysis due to injury. “About a hundred years ago, people started asking why it was impossible to get the axon to regenerate upon injury,” said Zhigang He, Harvard Medical School assistant professor of neurology at…
