Amelia Nurse talks to Belgian neurosurgeon and brain researcher Dirk De Ridder about the five stages of drug induced spiritual experiences; how repetition - of anything - can change your brain; whether religiosity is genetic; god as a phantom experience; and whether science can prove or disprove the existence of god. Dirk De Ridder was recently appointed as the inaugural Neurological Foundation Professor of Neurosurgery at the University of Otago.
