Is Optogenetics the Key to Solving Disorders of the Brain and Prosthetics?

I found this story though Engadget, but it’s a story coming from Wired, where it goes through the fledgling history of a relatively new field of neuroscience, Optogenetics. Its is the study of using light and modified genes (inserted using modified viruses) to try and alter the brain to cure disorders like Depression and Parkinson’s! The trials from Stanford haven’t gotten past the animal stages yet, but they have started working on rhesus monkeys (which have very similar brains to humans) and already got Parkinson’s mice literally up and running again. The whole thing is very new, but very cool, especially if we can start using blue light to activate brain cells, yellow light to quiet them and green light to send response signals by activating different forms of rhodopsin (Channelrhodopsin-1, Channelrhodopsin-2 and Halorhodopsin).

Check out the article here to get the details, this could be very cool for diseased brains very soon.

Thanks to Wired for the above pic.
