Two new maps illustrate human and mouse brains in sharp relief, offering insights into how brains are built and operate. The studies, led by scientists at the Allen Institute for Brain Science in Seattle and published  April 2 in Nature, join other recent large-scale descriptions of the brain (SN Online: 3/27/14; 2/17/14).
