Another area around music and brain caught my eye today.
Eduardo Miranda (1) is featured in the BBC report http://www.bbc.co.uk/news/uk-20799961
for his work in Brain Computer interfaces(2).
His research at Plymouth university (3) where ‘music’ meets ‘avatar’, is funded to breakdown Beethoven’s seventh symphony and reinterpret the music on a computer as heard by 3 individuals, a ballerina, a gulf war veteran and Dr Miranda himself.(4)
All the subjects underwent functional magnetic resonance imaging (fMRI) scanning to take pictures of the emotional responses to the music in the brain so that they could be reapplied to the 2nd movement of Beethoven’s 7th symphony.
Listening to the BBC report is fascinating, as you can hear the difference between the ballerina’s more jerky interpretation of the music (Dr Miranda puts this down to her possible use of body movement in interpretation of music), whereas Dr Miranda’s version is more fluid and different instruments are more audible, he thinks this is because he hears it as someone who plays the piano.
The brain computer interface has also been used by Dr Miranda’s team to help someone with ‘locked in syndrome’ (5) to make music from their brainwaves. Electrodes trigger music from the brainwaves.
The results are a bit weird, but they are wonderful, and Dr Miranda hopes to utilise the technology to perhaps invent a prescription of musical health for people suffering from depression and other emotional health problems, by identifying patterns of brain waves and changing them.
Maybe one day this will even help epilepsy?!
