Neurologist and author Oliver Sacks has come across plenty of odd stories while studying the human brain, but none are quite as mysterious as that of his colleague, Tony Cicoria. In 1994, Cicoria was struck by lightning, and developed a sudden, inexplicable passion for playing and writing piano music. In this podcast, hear Sacks describe Cicoria's transformation.
