Martha Brody opted to weather two brain procedures this year in an effort to end the grand mal seizures that have punctuated her life since freshman year in high school. First, in March, 17 electrodes were placed into small holes drilled into her head to give specialists in the Epilepsy Monitoring Unit at John R. Oishei Children's Hospital a better sense of what was causing the seizures, including four that struck within the previous year. A tiny portion of her brain that helped put the seizures in motion was removed in late May. She was awake for about half that procedure, in which a surgical team also embedded a device into Brody’s skull and pair of electronic leads into her brain. That NeuroPace implant is designed to work almost like a cardiac pacemaker in reverse – in this case, short-circuiting a seizure when warning signs appear. “It was surreal,” said Brody, 30, who is convalescing with her parents in her native Williamsville. She plans to resume her job … [Read more...] about Williamsville woman turns to brain implant to short-circuit her seizures

Lightning had struck the building. But the appliances were not the only things affected. After about an hour, the woman, who had had the electrodes put in five years before to help with debilitating muscle spasms in her neck, noticed her symptoms coming back. When she went to see her doctors the next day, they found that the pacemaker-like stimulator that powered the electrodes had switched itself off in response to the lightning strike. In a study describing these events published Tuesday in the Journal of Neurosurgery, her doctors suggest that … [Read more...] about Lightning Struck Her Home. Then Her Brain Implant Stopped Working.
A lightning strike that hit a woman’s apartment in Slovenia shut down her brain implant in addition to destroying both her TV and air conditioner. The device was not destroyed like the others, according to U.S. News and World Report, but the woman noticed about an hour later that her neck tremor was returning and realized that the device had shut down. She had to go to the hospital the next day to have it reset. It was the first report of a brain implant being affected by lightning, and Dusan Flisar of University Medical Centre in Lubljana said the strike might have been fatal if the user had been recharging the device by plugging it in at the time, New Scientist reported. “If a huge surge of electricity enters the system, it could be conducted into the brain — we don’t know,” Flisar said, New Scientist said. Brain stimulators are used to treat movement disorders like Parkinson’s as well as dystonia that can cause involuntary contractions of … [Read more...] about Lightning Strike Shuts Down Woman’s Brain Implant
What if we could edit the sensations we feel; paste in our brain pictures that we never saw, cut out unwanted pain or insert non-existent scents into memory? University of California, Berkeley neuroscientists are building the equipment to do just that, using holographic projection into the brain to activate or suppress dozens and ultimately thousands of neurons at once, hundreds of times each second, copying real patterns of brain activity to fool the brain into thinking it has felt, seen or sensed something. The goal is to read neural activity constantly and decide, based on the activity, which sets of neurons to activate to simulate the pattern and rhythm of an actual brain response, so as to replace lost sensations after peripheral nerve damage, for example, or control a prosthetic limb. "This has great potential for neural prostheses, since it has the precision needed for the brain to interpret the pattern of activation. If you can read and write the language of the brain, you can … [Read more...] about Editing brain activity with holography
The convergence of artificial intelligence and brain-computer interfaces may soon restore sight to the blind, allow the paralyzed to move robotic limbs and cure any number of brain and nervous system disorders. But without regulation, this flurry of innovation spells trouble for humanity, warns a team of researchers led by Columbia University neuroscientist Rafael Yuste and University of Washington bioethicist Sara Goering. In a new essay in Nature, Yuste and Goering join more than two dozen physicians, ethicists, neuroscientists, and computer scientists, in calling for ethical guidelines to cover the evolving use of computer hardware and software to enhance or restore human capabilities. "We just want to ensure that this new technology which is so exciting, and which could revolutionize our lives, is used for the good of humankind," said Yuste, director of Columbia's Neurotechnology Center and a member of the Data Science Institute. Long the stuff of science fiction, the melding of … [Read more...] about Experts call for ethics rules to protect privacy, free will, as brain implants advance
