Dr. Bianca Wittman of University College London found that making novel choices activates the ventral striatum of the brain. This area is associated with rewarding behavior.

Also, familiar brands also cause higher levels of brain activation, so the perfect pitch may be a new product from an established brand. Hmm, "Apple iPhone," maybe? Read more about the study here
