A Brain–Computer Interface Allows Paralyzed Patients to Play Music with Brainpower Alone

brain computer interface for music

A pianist plays a series of notes, and the woman echoes them on a computerized music system. The woman then goes on to play a simple improvised melody over a looped backing track. It doesn’t sound like much of a musical challenge — except that the woman is paralysed after a stroke, and can make only eye, facial and slight head movements. She is making the music purely by thinking.

This is a trial of a computer-music system that interacts directly with the user’s brain, by picking up the tiny electrical impulses of neurons. The device, developed by composer and computer-music specialist Eduardo Miranda of the University of Plymouth, UK, working with computer scientists at the University of Essex, should eventually help people with severe physical disabilities, caused by brain or spinal-cord injuries, for example, to make music for recreational or therapeutic purposes. The findings are published online in the journal Music and Medicine.

Boffins Create Thought-Controlled Computer

According to this Register article Boffins at the EC’s Joint Research Centre have created a thought controlled computer.

The computer works by picking up the electromagnetic signals created in the brain when people think of different things. Electrodes attached to a plastic cap which is put on the user’s head pick up the signals. Then by tying in thought patterns with different, simple instructions the computer can be controlled by thought alone.
