“This book has come at an important time in the evolution of the brain machine interface … Unlocking Erik tells the story from the human side – both in terms of Erik himself as the subject, and Dr. Kennedy as the pioneer. It is a journey of quiet and slow discovery, and has taken courage and risk from all sides.” -- Professor Alexander Green, Neurosurgeon, University of Oxford, England.

“With Dr. Kennedy widely regarded as one of the pioneers of this technology, he is uniquely placed to discuss the far-reaching consequences and ramifications of BCI, and this certainly helped attract the funding we needed to begin production of the documentary that tracks early breakthroughs in the field.” -- David Burke,Dot Television, Ireland

“Finally, with all the excitement of machine learning, we shouldn’t forget that we are talking about connecting to a neural network with more capabilities and far more creativity than anything that Google has made – the human brain! So let’s try to not forget the brain’s ability to learn.” -- Andrew Jackson, Professor of Neural Interfaces, University of Newcastle, U.K.

"We know that neurons involved in internal "thinking" are also clearly controllable. As explored in Phil Kennedy's study of Erik, the neurons involved in generating speech are a particularly important group of volitionally controllable neurons for speech prostheses." -- Eberhard Fetz

"This book tells a remarkable story. There is a group of patients rendered unable to communicate by a brutal medical misfortune. There is a new therapy involving special equipment... and there is the physician who manages their care... Dr. Kennedy has achieved remarkable success with his brain machine interfaces. He remains focused on the tremendous value of restoring speech to patients who are trapped inside their own bodies..." -- Thomas Wichmann
