Spinal cord injuries often lead to paralysis of the lower extremities due to the severing of the connection between the brain and the lower spinal cord. To solve this problem, scientists at Brown University (USA) have developed a system that bypasses the damaged area and wirelessly connects healthy parts.
This is not the first such development. In particular, special implants were used to stimulate the local network of nerves in the lower spine, which do not require brain commands. To restore movement, signals from sensory input were supplied.
Another area involves the direct transmission of brain signals to the muscles of the limbs bypassing the damaged spinal cord using an electronic implant implanted in the brain. Its principle of operation is to read brain commands given to parts of the body and transmit them to a computer. The main problem was the wired way of transmitting information.
The new technology involves the use of wireless sensorineural transmission of signals from a chip implanted in the brain to a computer, which decodes them and transmits them wirelessly. An impulse generator is implanted into the lower part of the spine, which converts these signals into electrical impulses that mimic the usual commands from the brain to contract muscles.
The system is currently being tested on monkeys.
