A team of South Korean scientists has developed a new labelling technology that can observe neuronal structure in detail and help decode degenerative brain disorders like Alzheimer's and Parkinson's disease, as well as stroke -- known to cause malfunction and progressive degeneration of the nerve cells.

The next-generation technology, named 'NeuM' (Neuronal Membrane-selective), enables successful monitoring of neuronal changes for up to 72 hours, said the team from the Korea Institute of Science and Technology (KIST).
