Play this musical instrument with just your thoughts
Good news for people who hate practicing scales:
scientists have created a musical instrument you can play with just your
thoughts.
The instrument, called the Encephalophone — “enceph” means “head” — is described in a paper published in the journal Frontiers in Human Neuroscience.
It’s not just a source of fun for the lazy but musically ambitious
among us; the researchers hope that one day this brain-computer
interface can help people with motor disorders.
That’s in the future, though. Today’s study was done with
15 healthy participants. To work the Encephalophone, they put on a cap
that can measure electrical signals in the brain. In this case, the cap
recorded two kinds of brain signals. One type is produced when you close
your eyes and the other when you think about making movements.
The cap turns brain signals into notes, which are then
played using a synth. With no training, all the participants could play
it easily. The cap was more accurate when the participant tried to
control it by closing their eyes, though the scientists are ultimately
more interested in what happens when they think about moving.
The hope is that the Encephalophone can be a tool used in rehabilitation. Music is already used
to help people regain brain function, and the instrument could be used
in this type of therapy. It’s also possible, the authors write, that
combining the Encephalophone with physical therapy could help rewire key
circuits in the part of the brain responsible for movement.
There’s plenty left to do before we get there, however.
For now, the researchers want to make the Encephalophone more
sophisticated and able to produce a wider range of sounds. Next, they
will test how much people can improve with some training and will begin
clinical trials with disabled people later this year. Maybe one day
we’ll all be able to create music with nothing more than a cap and what
our brains can produce.Via theVerge
