About The Cover

Just as the ancient navigators depended on maps and charts to explore the unknown, investigators today are building maps and charts with which to explore new scientific frontiers. This issue contains a special feature, The Human Genome Map 1990 (page 262-262p), and special articles and reports relating to genome mapping and the neurosciences.
