Recommendation

The intricate connections between the human brain and bodily movements are slowly being decoded, with new brain-machine interface (BMI) technology. Richard Andersen’s CalTech research team is implanting electrode arrays directly into the brain, which allows subjects to move prostheses, and in some cases actually feel the movements, through a new generation of “read-out” BMIs. The results give hope to everyone with brain damage or degenerative nerve diseases, that they can learn to move and manipulate their world by simply thinking about it, opening their lives to more freedom and independence. 

Take-Aways

  • Neuroscientists have labored for decades to find ways to connect human brain impulses to physical actions, with limited success.
  • Newer “read-out” BMIs record and translate neural activity, which could benefit people with spinal cord injuries and degenerative nerve diseases.
  • Experiments with tetraplegic spinal cord patients proved that BMIs can work in at least 180 areas of the brain.
