It is often said that, given an infinite amount of time, monkeys hitting random keys on a typewriter will eventually type the works of Shakespeare. While it may seem far fetched, an unusual experiment has achieved the fabled task. To illustrate how paralysed people can type using a device called a'brain-computer interface', scientists used monkeys to show how it can be done. Two rhesus macaque monkeys (stock picture left) had electrodes implanted in part of the brain that controls hand movement. As a result, they were able to type a passage from William Shakespeare's Hamlet The technology uses a multi-electrode array implanted in the brain to directly read signals from a region that directs hand and arm movements used to move a computer mouse.
