Jananathan Wallow, a doctor from the United States, have created a device that makes possible the communication of paralyzed patients. The device is a "cap" with electrodes attached to the human head and removes the signals sent to the brain.
Communication takes place as follows. The patient fixes his eyes on one of the letters on the monitor, and the device registers the alarm brain and projects the letter on the screen. So dumb people can pass whole words and sentences.
Jonathan Wallow believes that the device requires some modifications. While processing a single letter takes about 15 seconds. However, the principle of operation of the device deserves attention. It is possible that in the future such devices will become the basis for communication paralyzed patients with loved ones.
