Mice lacking the protein REST (bottom) showed much higher neural activity in the brain than normal mice.

Several snapshots show a C. elegans worm making a gradual turn in response to false sensory information. Using lasers, researchers were able to take over the worm’s brain and instruct it to turn in any direction they chose. They implanted false sensory information, fooling the worm into thinking food was nearby. By taking control of such complex behaviors, researchers hope to understand how a worm's nervous system functions.
