Brain-computer interface successfully translates thought into synthesized speech

In a pioneering study, scientists have demonstrated that an implanted brain-computer interface (above) coupled with deep-learning algorithms can translate thought into computerized speech. Read the rest

Lightning knocks out woman's brain implant

Deep brain stimulators -- pacemaker-like implants that deliver electrical impulses to specific regions in the brain -- are common treatments for Parkinson's and other neurological disorders. It's known that strong electromagnetic fields from the likes of ham radio antennae and arc welders can damage the devices. Now, researchers report the case of a 66-year-old woman whose deep brain stimulator was knocked out when lightning hit her apartment. Fortunately, the lightning shut off the device without damaging her brain.

“The patient was not charging the battery of her IPG (implantable pulse generator) during the event, and the recharger for the IPG was disconnected from the power supply during the storm," the researchers wrote. "The recharger and IPG were therefore not destroyed. The patient realized that something was wrong only 1 hour after the storm subsided, when the dystonic tremor in her neck reappeared.”

Scientists remote control a mouse with a wireless LED brain implant

Stanford scientists made mice walk in circles via remote control of a wireless LED implanted in the rodents' brains. Switching the LED on and off controls neurons that have been previously genetically engineered to be light-sensitive. Read the rest
