" With no more than a slight pop, language was gone. The vanishing was so complete, I didn’t even know what I’d lost because the entire concept of words and the ability to string thoughts together simply disappeared. One moment there was a dialogue playing in my head, a little voice saying, I wonder what’s going to happen when they do this. The next moment, the voice was gone. All that remained was feeling. The comfort of the chair, and a sense of familiarity with the people beside me. I was incapable of a realization like “I can’t talk!” since it consists of words. Without words I had ceased to be a creature of coherent logical thought. Instead, I lived in the moment with sound, sight, smell, and feeling. "

" The concept of “brain plasticity” refers to the ongoing capacity of the brain and the nervous system to change itself. Everything that we do, think, feel, and experience changes our brain. A stroke or a traumatic brain injury can affect brain plasticity, and plasticity may also be associated with such developmental disorders as autism. Increased brain plasticity may also potentially endow a person with unanticipated new abilities, as John appears to have experienced in this book. TMS, or transcranial magnetic stimulation, the intervention that John undergoes, provides a unique opportunity for us to learn about the mechanisms of plasticity, and to identify alterations in the brain’s networks that may be responsible for a patient’s problematic symptoms, and also for recovery.
