I have no military application in my research. You know, we are all involved into rehabilitation medicine.

There are several patients - there are thousands of patients, tens of thousands of patients, that carry either a stimulator in the brain or in the periphery, in the inner ear, to restore neurological functions or to control diseases like Parkinson's disease.

I think the word 'soul' - it depends on what you define by 'soul.' If you're defining it as a mystical aura that is outside the body, I cannot measure that. If you're talking about soul as human nature, the rank of spectrum of behaviors and reactions that we know humans produce under certain circumstances, that is measurable.

Eventually, brain implants will become as common as heart implants. I have no doubt about that.

With its billions of interconnected neurons, whose interactions change from millisecond to millisecond, the human brain is an archetypal complex system.
