Light Helps Injured Mice Walk Again 92
Mantrid42 writes "Researchers have been able to affect the brains of lab mice using light. Working in a new field called Optogenetics (optical stimulation plus genetic engineering), scientists injected lab mice with genes that can stimulate or inhibit neural activity based on the color of the light they're exposed to, and can be targeted to infect only on certain cell types. Additionally, another gene has been added to make neurons glow green when firing, allowing two-way communication between a brain and a machine."

i'm aware that computational simulation is often faster then taking a biological neuron _now_, but such a "computer" would be a wonderful platform for testing and learning about how neurons really *work* - it's like incredibly complex constraint system in programming (i mean, constraining one value to the value of something else)

This is the DNI we've been waiting for... The surgeon pops open your skull, injects some strategic locations with some gene altering viruses and installs some flashing lights. Now you can do two-way communication with a computer. What you experience depends on which cells were modified, and what program you're running. With sufficient funding for targeted research, we could see this technology in new kinds of: cochlear implants for the deaf, vision implants for the blind, artificial limb control and feeling for amputees.. and the continued improvement of those technologies will eventually lead to full sensation virtual reality immersion for anyone who can afford it. And we haven't even gotten into the gritty details of what we can learn about the brain using this technology.. reverse engineering is so much easier when you can poke as well as peek.
