It is known that brain–computer interfaces record brain activity and translate the information into useful control signals. They can be used to restore function to people with paralysis by controlling end effectors such as computer cursors and robotic limbs. Communication neural prostheses are brain–computer interfaces which control user interfaces on computers or mobile devices, with directly reading brain signals a highly desirable technology.  Now, a … Continue reading New technology for reading signals directly from the brain allows typing at 12 words per minute.
