How to compose classical music with your brainwaves
This new project from Professor Eduardo Miranda allows you to compose music with your brainwaves, from bbc.
Joel told me the main electrode at the back of my head would pick out brainwaves from my visual cortex while the other electrodes would essentially help to cancel out any background noise.
Operating the device requires the user to concentrate on one of four chequered patterns. These all flicker at different rates and each pattern makes the visual part of the brain create a sympathetic electrical signal.
The signal gets picked up by the brain cap and sent to the computer. The device works best when the rest of the brain is relaxed, so “clearing your mind” is encouraged.
The brain’s electrical signals are amplified then sent to a laptop.
Joel encouraged me to stare at the pattern in a very particular way, a bit like focusing and defocusing. Sometimes I’d have to look away from the screen and look back to refresh my brain.
