Could technology replace pills and prescriptions?

   

Bioelectronic medicine may one day let us tap into our own nervous systems.
Imagine a day when you go to the doctor and, instead of a prescription on paper, you come out with a tiny device attached to your nervous system and possibly a new app on your phone. No more worrying about what time you have to take a pill – all you need to do is let technology do its business. Believe it or not, this day may not be that far away.
The human nervous system is the bioelectrical infrastructure of your body. Now imagine you could hack it. Welcome to the field of bioelectronic medicine. It’s an area that asks: what if, instead of using drugs to treat a condition, implants could control and tweak our body’s functions? What if, somewhere down the line, you could combat a tumour by harnessing your neural signals?

The idea may sound far-flung, but the research around it has roots in one of the most common bodily responses – one that most of us have likely experienced at one point or another.

The brain can interact directly with virtual reality .

Not only science fiction is the idea that the brain can be directly linked to a Computing virtual world, as imagined in the film "Matrix".
Scientists led by Rajesh Rao, University of Washington, have managed to do the first step to show, through a video game, that human beings can interact with virtual realities by stimulating the brain.
In this study published in the journal "Frontiers in Robotics and AI", the researchers describe what's demonstration of the first people to play a video game simply by using only the data coming from the stimulation of the brain, without using any kind of signal that comes out of sight, hearing and touch.
