Implication

New devices deliver targeted optical stimulation in small rodents, suggesting advances for neuromodulation techniques.

Key Points

  • To develop a fully implantable, battery-powered system for innovative optogenetic stimulation of the spinal cord in small rodents.
  • Created a wireless, battery-operated device for spinal cord light delivery.
  • Integrated multiple µLEDs and a rechargeable battery in a compact design.
  • Validated device stability and functionality in small rodents over a month-long period.
  • Successfully demonstrated operator-free paralysis of hind limbs via targeted optical stimulation.
  • Maintained device functionality and stability in various housing environments.
  • Achieved minimal adjustments for stimulation at different spinal cord levels.
