Normally,
you have to stay absolutely still during an MRI, but in this research
scan, scientists wanted to study the movements of the head and throat
muscles during singing. The overall goal of the research is to see if
singing in a group chorus can help people in retirement homes build
stronger voices. To do this at all, a team of an electrical engineers
developed a scanner that would record 100 frames a second -ten times the
normal rate. Enjoy this volunteer singing an appropriate song, and then
go to mental_floss to read about the research involved.
