“It’s at the systems level with brain imaging that you can directly
correlate mental states and brain states — and measure them.”
Silbersweig says. “Neuroimaging provides a noninvasive way of
correlating brain structural and functional abnormalities with specific
aspects of music processing.” For example, Silbersweig has seen people
who survive stroke or tumors develop sensory amusia, a condition
resulting from a lesion in the brain’s right superior temporal gyrus.
Because this region is integral to recognizing disparate sounds as part
of a cohesive work, patients with sensory amusia lose the ability to
perceive or respond to music. While patients with this condition may not
be able to revive damaged tissue, exposure to music itself can
indirectly make up for the setback.
