“This new wireless system addresses a major need for the next step in providing a practical brain-computer interface."
|David A Borton et al./J. Neural Eng.|
A team of neuroengineers 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 open-access 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.
Neuroscientists can use such a device to observe, record, and analyze the signals emitted by scores of neurons in particular parts of the animal model’s brain.
