Amusia and musicogenic epilepsy.

Amusia and musicogenic epilepsy are clinical disorders that provide a window into the localization of music in the brain. Classic clinical studies of patients with these disorders, coupled with more recent studies employing modern neuroimaging and sophisticated neuropsychologic paradigms, have converged in helping to elucidate the complex neural systems that are utilized in decoding music. The notion of cerebral dominance for music has been replaced by a concept of modular but interconnected networks that have wide bilateral localization in the brain and that are molded both by genetics and experience. These disorders also provide insight into the important interface between music and emotion.
