Can a new brain-circuit model change our thinking about neurodegenerative disease?

If you're diagnosed with Huntington's disease, your treatment would be no more effective today than on the day of its discovery ... in 1872. Why has progress treating brain diseases been so slow? After 20 years of research, neuroscientist James Kozloski has come to a startling conclusion: Scientists are thinking too small. He looks past the usual genes that cause the diseases with a new brain model that maps the brain's core components and connects them into a single circuit. The implications of his research carry weight for Huntington's, and far beyond.
