Direct brain communication: a new book

Images of the brain, created with advanced technology, are known to most of us. But progress in neuroscience is fast. Less familiar are new technical opportunities to communicate directly with the brain … or however you put it!

Even the unconscious brain is alive. It has been possible to depict responses in the “unconscious” brain to what occurs in its environment. In some cases one has been able to establish communication, where the “unconscious” patient answers yes/no-questions by thinking of one thing if the answer is “yes” and on another thing if the answer is “no.” This activates different parts of the brain. Since researchers/doctors can detect which part of the brain is activated, the patient can answer questions and communicate with the outside world. (Here is an earlier post on this.)

Other examples of this development are new interfaces between brain and computer, where people learn to control a computer, not through the muscles, but via electrodes connected in the brain. People who cannot communicate verbally can thus get computer support. They can also learn to control prostheses. The brain is obviously exceptionally plastic and interactive!

A new anthology, with Michele Farisco and Kathinka Evers from CRB as editors, systematically assesses the philosophical, scientific, ethical and legal issues that this development implies: Neurotechnology and Direct Brain Communication (Routledge, 2016).

The book addresses scientific and clinical implications of the possibility to communicate with patients who may not be quite as unconscious as we thought. Perhaps we should rather talk about altered states of consciousness. But also infant care is discussed, as well as ethical and legal issues about authority, informed consent and privacy.
