How thoughts can control a flying robot
It’s a staple of science fiction: people who can control objects with their minds.
At the University of Minnesota, a new technology is turning that fiction into reality.
In the lab of biomedical engineering professor Bin He, several young people have learned to use their thoughts to steer a flying robot around a gym, making it turn, rise, dip, and even sail through a ring. (more…)
In a significant advance for brain-machine interfaces, engineers at Brown University have developed a novel wireless, broadband, rechargeable, fully implantable brain sensor that has performed well in animal models for more than a year. They describe the result in the Journal of Neural Engineering and at a conference this week.
PROVIDENCE, R.I. [Brown University] — A team of neuroengineers based at Brown University has developed a fully implantable and rechargeable wireless brain sensor capable of relaying real-time broadband signals from up to 100 neurons in freely moving subjects. Several copies of the novel low-power device, described in the Journal of Neural Engineering, have been performing well in animal models for more than year, a first in the brain-computer interface field. Brain-computer interfaces could help people with severe paralysis control devices with their thoughts. (more…)
ANN ARBOR, Mich.— Chronic migraine sufferers saw significant pain relief after four weeks of electrical brain stimulation in the part of the brain responsible for voluntary movement, the motor cortex, according to a new study.
Researchers from the University of Michigan School of Dentistry, Harvard University and the City College of the City University of New York used a noninvasive method called transcranial direct current stimulation (tDCS) as a preventative migraine therapy on 13 patients with chronic migraine, or at least15 attacks a month. After 10 sessions, participants reported an average 37 percent decrease in pain intensity. (more…)
