Optogenetics and Bio-luminescence
I was watching Ed Boydens TED speech, A Light Switch for Neurons, and have a question/suggestion concerning how to deliver light to the brain. Attaching optical fibers seems to be the least exacting aspect of this research. If one can use gene vectors such as viruses to deliver instructions for neurons to develop proteins that react to light, it seems reasonable to assume that one could also insert genes to produce light? There are many organisms that exhibit bioluminescence. Inserting genes for bioluminescence could allow for a much more precise delivery of light to specific neurons than using optical fibers.
