Nanotechnology, neuroscience, bye bye free will..

In June 2009. Honda came up with a new Brain-Machine Interface helmet that gave the user power to communicate telepathically with humanoids. It reads your thoughts by measuring changes in electrical current and blood flow in the brain.

Things have moved on from then. Developments in nanotechnology means that data can now flow in two directions.
take the New Scientist article (reported in io9): " For the first time ever, scientists can control human brain cells using quantum dots
What if you could treat conditions ranging from Alzheimer's to blindness, all with a flash of light? Researchers think it's possible — and they plan on using tiny particles called quantum dots to do it.
Brain stimulation can be incredibly tricky. Performing it from outside the head is effective, but doesn't give you very much specificity when it comes to turning on a specific brain region...Recently, researchers have sought out solutions to these problems with methods that rely on light, in hopes that they can be used to stimulate brain activity with a high level of precision without having to crack your skull open. Right now, the buzz-word in light-mediated brain stimulation is optogenetics, which looks incredibly promising, but relies on genetic modifications that are still considered too risky to test in humans."


Nerve cells like these could be controlled by quantum dots.

What next?
DNA is now being used as a template to bioengineer nanoparticles that are able to attach to and reside in living organisms. In fact nanotechnologies have been developed that draw their energy from the body.
So it's no long shot to expect the emergence of nanotechnology implants that enable us to directly control electronics and machinery - or be controlled. Oh dear!
