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.

No real evidence has been produced to prove that this new technology is safe in the long term. Until it is, I think we should take a precautionary approach and use cabled systems.

It should be noted that most wireless routers output less energy than most cell phones.
