Communication For People With Disabilities-Music Science

Communication for people with disabilities through music science.  The Center for Genomic Regulation, Starlab and the University of Barcelona present Brain Polyphony started a project that focuses on improving communication for people with disabilities.


Polyphony is a texture of two or more simultaneous lines of independent melody, as opposed to musical texture that is one voice – known as mono-phony. Indifference from musical texture with a single dominant melodic voice with chords is called homo-phony.

Cognitive neuroscience of music

The neuroscience of music is the scientific study of brain-based mechanisms that are in the cognitive processes underlying music.  These behaviors include listening to music, composing, reading and performing.  It is also increasingly concerned with the brain and musical emotion and aesthetics.


This is the scientific study of the nervous system.  It is a multidisciplinary branch of biology that includes:

  • physiology
  • anatomy
  • molecular biology
  • developmental biology
  • cytology
  • mathematical modeling
  • psychology
  • neurons
  • neural circuits

Scientists at the Center for Genomic Regulation, the research company Starlab and the group BRAC (Barcelona Research Art & Creation) of the University of Barcelona developed a device that produces sounds for signals in the brain.

The Team is led by Mara Dierssen, head of the Cellular & Systems Neurobiology group at CRG.  Its main goal is to create an alternative communication system for people with cerebral palsy to allow communication and to communicate with their emotions.

Mara Dierssen told the disabled world:

“At the neuroscientific level, our challenge with Brain Polyphony is to be able to correctly identify the EEG signals-that is, the brain activity – that correspond to certain emotions.  the idea is to translate this activity into sound and then to use this system to allow people with disabilities to communicate with the people around them.  This alternative communication system based on sonification could be useful not only for patient rehabilitation but also for additional applications, such as diagnosis.”
