The Neuroscientist Who Tested a Brain Implant On Himself

An anonymous reader writes: Our understanding of the brain has come a long way in the past thirty years, but most brain-related medical procedures remain incredibly complicated and dangerous. Neurologist Phil Kennedy has been working on brain-computer interfaces since the 1980s. He was most notably involved in letting a patient with "locked in" syndrome interact with the outside world through a brain-controlled computer cursor. But the FDA has gradually ramped up its safety demands, and in the past decade they've shut down Kennedy's research. So he did what any determined inventor would do: he went to a hospital in Belize and had surgeons there implant electrodes on his own brain so he could continue his research. "After returning home to Duluth, Georgia, Kennedy began to toil largely alone in his speech lab, recording his neurons as he repeated 29 phonemes (such as e, eh, a, o, u, and consonants like ch and j) out loud, and then silently imagined saying them. ... Kennedy says his early findings are 'extremely encouraging.' He says he determined that different combinations of the 65 neurons he was recording from consistently fired every time he spoke certain sounds aloud, and also fired when he imagined speaking them—a relationship that is potentially key to developing a thought decoder for speech." Eventually, Kennedy had to have the implants removed, but he hopes the data he gathered will help push the FDA toward supporting this research once more.
