ONLINE COVER A Guiding Light. For most, the thought of controlling human behavior and treating neurological diseases with light seems like science fiction. But a maturing field, called optogenetics, works to combine gene therapy with light-based cues to turn such fiction into reality in the clinic. As shown on this week’s futuristic cover, an array of thin, microsized silicon waveguides has been designed to deliver light to multiple targets in three-dimensional space within the brain. Currently being tested in animals, this optogenetic technology could soon find its way into humans. Perspectives in this issue from Chow and Boyden and from Williams and Denison highlight the scientific, practical, and regulatory hurdles that need to be cleared before translation is possible.
