Brain Implants Lets Paralysed People Use Computers with Thoughts
Many people across the world live with some type of paralysis today, but scientists from Australia have developed technology that could prove to be revolutionary for people with limited mobility.
Professor Peter Mitchell, the Neurointervention Service Director and head of the study at the University of Melbourne, and his team have created a device – no larger than a paperclip – that allows patients to control computers with just their brain.
The study involved two patients undergoing surgery to implant the device, which is called “Strentrode.” Both individuals have amyotrophic lateral sclerosis, which has left their upper limbs paralysed.
The Strentrode is wireless, and flexible enough to pass safely through the blood vessels in the brain. The procedure to install it is not unlike that of a pacemaker, and no open brain surgery is required.
The implant interfaces with the person’s brain, and – with an eye-tracker – allows them to move the cursor on screen without using their hands.
The results are certainly exciting and provide a launching pad for other technologies that could improve freedom of movement for individuals who are differently abled.
