From Thought to Speech in 600 Milliseconds (1 of 4) (image) American Association for the Advancement of Science Share Print E-Mail Caption This is an X-ray showing electrodes that surgeons use to find and remove the source of seizures (to cure epilepsy), while sparing the source of mental functions like language. In this study, recordings when patients spoke words revealed that one small part of the brain computes the meanings, structure, and sounds of words, separately and in a quick sequence. It is important to note that electrodes are only implanted in people's brains as part of existing and accepted surgical practice. We then get patients' consent to also record from these electrodes for research purposes. Electrodes are never implanted just for research.
