But do musicians with perfect pitch have different brains?

The study compared the auditory cortex (the part of the temporal lobe that processes auditory information) structure of 61 age and sex matched groups of musicians with Absolute Pitch, musicians without Absolute Pitch, and a control group of participants without any musical training.

While Absolute Pitch “is associated with a number of gross morphological changes in the brain,” the authors – Larissa McKetton, Kevin DeSimone and...
