Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Systems Biology

Background:

  • Decoding neural signals allows brain-machine interfaces (BMIs) to control external devices.
  • Electrical stimulation of sensory areas can provide artificial sensory feedback.
  • Combining neural recording and stimulation enables closed-loop systems with emergent behaviors.

Purpose of the Study:

  • To investigate the concurrent regulation of bidirectional BMIs to shape desired system dynamics.
  • To create and test a neural interface emulating biological sensory-motor pathways.

Main Methods:

  • Developed a bidirectional neural interface for real-time communication between rat brains and an external dynamical object.
  • The interface included a motor component decoding motor cortical signals and a sensory component encoding object state into somatosensory stimuli.

  • Emulated the spinal cord's role in integrating motor commands and sensory feedback for coordinated movement.

    • Main Results:

    • The bidirectional interface successfully mediated interactions between brain activity and the external object's state.
    • The combined system demonstrated emergent dynamical behaviors, generating families of trajectories converging to equilibrium points.
    • The system exhibited prescribed reactions to perturbations, indicating stable and adaptable control.

    Conclusions:

    • It is possible to concurrently regulate bidirectional brain-machine interactions to achieve desired dynamical behaviors.
    • This novel interface successfully emulates biological sensory-motor loops, enabling sophisticated control.
    • The findings open possibilities for specifying not just movements but entire families of adaptable motions in closed-loop systems.
