Stimulating the brain : ethical perspectives on deep brain stimulation & nano scaled brain machine interfaces

Connecting man and machine through elaborate brain implants, known as Brain- Machine Interfaces (BMIs), does not only elicit technical and medical challenges and possibilities, but also many ethical concerns. The brain, sometimes described as the ‘seat of the soul’ or ‘organ of the mind’, provides the neural underpinnings not only for the individual human being and her unique characteristics, but also that which distinguishes human beings from nonhuman animals.
