Scientists believe they have discovered the part of the brain responsibile for remembering songs.
Only 10 other cases of musical hallucinations with dorsal pons lesions have ever been reported. All those patients suffered from severe disorders such as stroke, bleeding in the brain or an infection, and, in all but one of the cases, patients were alert and aware that they were hallucinating.
Musical hallucinations have also been reported in psychiatric patients, who think the music is real, and in elderly people who have chronic and extensive hearing loss. These latter hallucinations might be related to sensory deprivation, say experts.
