The article outlines the benefits and challenges of classifying neurons and highlights new genetic techniques for defining cell types.
In the August 7 issue of Science, science writer Emily Underwood elegantly lays out the historical background—dating back to the research of Santiago Ramón y Cajal—underlying The BRAIN Initiative’s goal of classifying the enormous variety of cells in the brain. Underwood goes on to spotlight a handful of new genetic techniques for cataloging neuronal diversity.
