Paralyzed Monkeys Able to Walk Again With Wireless Brain Device

The study has implications for humans

Two rhesus monkeys paralyzed by a spinal cord injury were able to walk again after scientists installed a wireless device in their brains to control movement, according to a new study.

Researchers hope that the breakthrough, reported in the journal Nature, can eventually be applied to humans with paraplegia. The device incorporates parts approved for human use and some have suggested the first human trials could take place by 2020.

Normally, the brain coordinates movement by sending electrical signals throughout the body using the spinal cord. People and animals with spinal cord injuries—like the lesions experienced by the monkeys in the study—can be immobilized because of the interruption. The new device sends wireless signals from the brain to “hotspots” that control different motions. In this case, the hotspots were installed on the lower spinal cord.

  1. “Paralyzed Monkeys Able to Walk Again With Wireless Brain Device” – good to see if the injuries were not done for the purpose of an experiment, (or is the result of a number of previous failures).
