A man who is completely paralysed uses a computer interface implanted in his brain to converse successfully.

The Wyss Center for Bio and Neuro engineering in Germany has accomplished the accomplishment of demonstrating medical and technology partnership. Two 3.2 mm square microelectrode arrays were implanted into the surface of the motor cortex, the portion of the brain that controls movement. There are 64 needle-like electrodes in each array that capture brain signals.

“This case study demonstrates that brain-based volitional communication is conceivable even in a totally locked-in condition,” according to the research. The scientists implanted 64 microelectrode arrays in the patient’s supplementary and major motor cortex.

They detected brain signals that the individual had trained to produce by performing various moves. The model interprets the signals as ‘yes’ or ‘no.’ A speller program reads the letters of the alphabet aloud to disclose what the participant want to convey. “Successful communication has already been proven with BCIs in persons with paralysis,” stated Jonas Zimmermann, PhD, Senior Neuroscientist at the Wyss Center in Geneva.
