The intricacies of brain function are intimately tied to the complexity of brain structure, both of which we are only just beginning to understand. New tools, technologies, and methods are allowing scientists to examine the nervous system in unprecedented detail, raising hopes of future therapies for neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis (ALS). This eBook takes a look at some of the approaches accelerating neuroscience discoveries.
