Translated roughly from Portuguese report in Diario do Sul: Neurosurgeon Dr. Mark Ghizoni last week performed surgery to extract a brain tumor extract in which the patient was kept awake.

In this procedure, he tests carried out during the operation were more complex than gestures or words exchanged between the patient and the surgical team. The 33-year-old patient sang and played guitar while the doctors performed the surgery. It began with a song he composed for his son, born a few months ago, followed by "Yesterday" by the Beatles, and other tunes.
