Via PopSci:
“Paralysis patients could play music with their minds, using a new brain-control interface that senses brain impulses and translates them into musical notes…
Patients with neurodegenerative disorders like Parkinson’s or Alzheimer’s can use music to walk to a rhythm or even to trigger memories or emotions. But stroke patients or those with locked-in syndrome can’t interact with music beyond just listening to it. With this system, patients with physical limitations might be able to use music for therapy, too — truly making music the medicine of the mind.”
This opens the possibility for extension into other forms of creativity, including (how did you guess?) art therapy!
