Consciousness and the Claustrum

"In biology, a reliable guide to understanding function is to study structure. Francis Crick and James Watson proved this idea spectacularly in 1953. They inferred the key function of DNA, the molecule of heredity—that is to say, storing and copying genetic information— from its double-helical chemical structure. Half a century later Crick, by then biology's most respected sage, tried his hand at the same game, linking a structure—the claustrum—to a function—the emergence of integrated, conscious experience."
