A microchip brain implant has helped a fully paralysed man to communicate with his family for the first time in years - one of his first words was 'beer'
A microchip brain implant has helped a fully paralysed man to communicate with his family for the first time in years.
The unidentified 26-year-old German man was diagnosed with amyotrophic lateral sclerosis , a rare progressive nervous system disease that leads to the loss of muscle control, in 2015. Researchers then trained the man to imagine physical movements to try and get a reliable signal from the brain.Researchers Ujwal Chaudhary and Niels Birbaumer then tried neurofeedback, in which a person is shown their brain activity in real time so they can learn how to control it.
When the implanted electrodes in the man’s brain recorded an increase in activity, a computer would play a rising audio tone. A fall in brain activity would play a descending tone.Before his condition progressed, family members would hold up a grid of letters against a background of four colours. Family members would point to each colour section and row, and interpret any eye movement as a ‘yes’.
