title: [Music and neurology].
abstract: Music perception and output are special functions of the human brain. Investigation in this field is growing with the support of modern neuroimaging techniques (functional magnetic resonance imaging, positron emission tomography). Interest in the music phenomenon and the disorders regarding its processing has been limited. Music is not just an artistic activity but a language to communicate, evoke and reinforce several emotions. Although the subject is still under debate, processing of music is independent of common language and each one uses independent circuits. One may be seriously affected and the other practically unharmed. On the other hand, there may be separate channels within the processing of music for the temporary elements (rhythm), melodic elements (pitch, timbre, and melody), memory and emotional response. The study of subjects with absolute pitch, congenital and acquired amusias, musicogenic epilepsy and musical hallucinations has greatly contributed to the knowledge of how the brain processes music. Music training involves some changes in morphology and physiology of professional musicians' brains. Stress, chronic pain and professional dystonias constitute a special field of musicians' disturbances that concerns neurological practice. Listening to and playing music may have some educational and therapeutic benefits.
