Optogenetics is the combination of deep brain stimulation with fiber optics and gene therapy.
I have read that there can be two way traffic (here (http://www.wired.com/magazine/2009/10/mf_optigenetics/all/1))
By injecting mice neurons with yet another gene, one that makes cells glow green when they fire, researchers are monitoring neural activity through the same fiber-optic cable that delivers the light. The cable becomes a lens. It makes it possible to “write” to an area of the brain and “read” from it at the same time: two-way traffic.
I know that there are no big or small firing of neurons - all firings are the same size. I was wondering if the fiber-optic cable can detect the difference between regular spiking, phasic bursting or fast spiking.
