RTTNews

Laser treatment has show promise in controlling drug addiction in rats, according to a research team at University of California, San Francisco. In their study, the researchers effectively turned cocaine addiction in rats on and off with the use of a laser and light-sensitive proteins implanted in the brain. The genetically engineered proteins, called rhodopsins, were administered into the nerve cells in the rats' prefrontal cortex. These proteins could then be activated and deactivated using a laser.
