Coloured lasers treat epilepsy?

A January, 2010, BBC health-related article claims that coloured lasers can be used to treat brain disorders, such as epilepsy. Apparently, the Massachusetts Institute of Technology has discovered a way to use yellow and blue flashing lasers to shut down brain activity.

The claim is initially unacceptable because lasers and epilepsy does not seem a common connection, nor a feasible one. The reader automatically questions, "what do colorful lights have anything to do with brain disorders?," and, "how can lasers cure seizures?" The answer to these questions is obviously not self-explanatory, and this is what begins the argument.
The article goes on to give details of the study and how and why it works. The author is giving reasons for the reader to believe the claim. The study revolves around two genes that need light to make energy. They are called Arch and Mach. Arch and Mac contain the genetic code for light-activated proteins. MIT has engineered brain neurons to express Arch and Mach. In testing they were able to control the brains of animals with yellow and blue lasers because the light activates proteins that lower the voltage in the neurons and stops them from generating an electrical signal. The researchers are working on targeting specific parts of the brain to shut down, eliminating seizures.
The author uses scientific facts and studies that show experiment outcomes to back up his claim. By the end of the article, a clear assumption is made that yellow and blue flashing lasers may one day cure brain disorders.
