George Gershwin (1898-1937) was one of the most influential American composers of the 20th century. Likewise his swift, comet-like, career progress from a high school dropout to an iconic composer of the 20th century: "The man who said he had more notes in his head than he could write down in a hundred years died suddenly ... in Hollywood".

(ii) Is glioblastoma and its connections with normal nerve cells, with noble tissue (a fact demonstrated in recent years), a cause that can trigger geniality, a different thought process from most people with a normal-functioning brain?
