Brain implant could help paralyzed patients walk

Australian researchers have created a bionic spinal cord that helps paralyzed patients walk.

Australian researchers have created a "bionic spinal cord" that could give paralyzed people hopes of walking again through the power of thought.

A tiny bionic spine can be implanted into a blood vessel next to the brain to read electrical signals and feed them into an exo-skeleton, bionic limbs, or wheelchair to give paraplegic patients greater mobility based on sub-conscious thoughts.

Measuring 3 centimeters long and a few millimeters wide, it requires a small cut to be made in the back of a patient’s neck. It is fed into the blood vessels that connect to the brain via a catheter. 

Once the bionic spine is implanted, the tiny electrodes on its exterior will stick to the walls of a vein and start recording electrical signals from the motor cortex.

These signals are then transmitted to another device implanted in the patient’s shoulder, which translates them into commands to control wheelchairs, prosthetic limbs, or computers via bluetooth.
